Recent Developments in Dehydrogenative Organic Transformations Catalyzed by Homogeneous Phosphine-Free Earth-Abundant Metal Complexes

Stoichiometric amounts of various oxidants have long been employed for the oxidation of organic compounds. The major drawback of this method is the amount of toxic waste produced, which is in sharp contrast to principles of green chemistry. In catalytic dehydrogenation pathways, hydrogen carrier organic compounds (HCOCs) containing O-H, C-H, and N-H bonds can be transformed to their oxidized forms by removing two hydrogen atoms from the starting materials. Among the homogeneous transition metal-ligand complexes that have been applied in a catalytic dehydrogenative approach, phosphine ligands have frequently been used. Over the past decades, phosphine-free ligand systems have since been developed and implemented in various organic reactions to overcome the drawbacks associated with phosphine-based catalysts. The aim of this review is to summarize the use of non-phosphinic ligand-metal complexes in organic transformations proceeding by a dehydrogenative pathway.

Synthetic Route of 3030-47-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 3030-47-5 is helpful to your research.

Thiocyanate-capped CdSe@Zn1-XCdXS gradient alloyed quantum dots for efficient photocatalytic hydrogen evolution

CdSe@Zn1-XCdXS QDs possessing a gradient alloy composition structure with an energy level width continuous increasing along the radial direction from the center to the surface were prepared and employed as a photocatalyst in a hydrogen generation system. Thiocyanate or mercaptopropionic acid capped QDs was adopted for assembling CdSe@Zn1-XCdXS QDs onto TiO2 film. Using as photocatalysts for hydrogen generation, it’s found that these gradient alloyed QDs/TiO2 photocatalysts exhibit excellent hydrogen production rates of 94 mmol/gh for MPA capped QDs and 951 mmol/gh for SCN capped QDs at 100 mW/cm(2) AM 1.5 illumination without co-catalysts. Moreover, the SCN capped QDs demonstrate remarkably higher hydrogen evolution rate than that of the reference MPA capped QDs due to a higher ligand induced hole trap level, resulting in a much faster electron-hole separation and charge transfer rate compared with those of MPA capped QDs.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3030-47-5 help many people in the next few years. SDS of cas: 3030-47-5.

Promoting CO2 methanation via ligand-stabilized metal oxide clusters as hydrogen-donating motifs

Electroreduction uses renewable energy to upgrade carbon dioxide to value-added chemicals and fuels. Renewable methane synthesized using such a route stands to be readily deployed using existing infrastructure for the distribution and utilization of natural gas. Here we design a suite of ligand-stabilized metal oxide clusters and find that these modulate carbon dioxide reduction pathways on a copper catalyst, enabling thereby a record activity for methane electroproduction. Density functional theory calculations show adsorbed hydrogen donation from clusters to copper active sites for the *CO hydrogenation pathway towards *CHO. We promote this effect via control over cluster size and composition and demonstrate the effect on metal oxides including cobalt(II), molybdenum(VI), tungsten(VI), nickel(II) and palladium(II) oxides. We report a carbon dioxide-to-methane faradaic efficiency of 60% at a partial current density to methane of 135 milliampere per square centimetre. We showcase operation over 18h that retains a faradaic efficiency exceeding 55%.

Dynamics of weak interactions in the ligand layer of meta-mercaptobenzoic acid protected gold nanoclusters Au-68(m-MBA)(32) and Au-144(m-MBA)(40)

Atomically precise metal nanoclusters, stabilized and functionalized by organic ligands, are emerging nanomaterials with potential applications in plasmonics, nano-electronics, bio-imaging, nanocatalysis, and as therapeutic agents or drug carriers in nanomedicine. The ligand layer has an important role in modifying the physico-chemical properties of the clusters and in defining the interactions between the clusters and the environment. While this role is well recognized from a great deal of experimental studies, there is very little theoretical information on dynamical processes within the layer itself. Here, we have performed extensive molecular dynamics simulations, with forces calculated from the density functional theory, to investigate thermal stability and dynamics of the ligand layer of the meta-mercaptobenzoic acid (m-MBA) protected Au-68 and Au-144 nanoclusters, which are the first two gold nanoclusters structurally solved to atomic precision by electron microscopy [Azubel et al., Science, 2014, 345, 909 and ACS Nano, 2017, 11, 11866]. We visualize and analyze dynamics of three distinct non-covalent interactions, viz., ligand-ligand hydrogen bonding, metal-ligand O = C-OHMIDLINE HORIZONTAL ELLIPSISAu interaction, and metal-ligand Ph(pi)MIDLINE HORIZONTAL ELLIPSISAu interaction. We discuss their relevance for defining, at the same time, the dynamic stability and reactivity of the cluster. These interactions promote the possibility of ligand addition reactions for bio-functionalization or allow the protected cluster to act as a catalyst where active sites are dynamically accessible inside the ligand layer.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Computational Mapping of Dirhodium(II) Catalysts

The chemistry of dirhodium(II) catalysts is highly diverse, and can enable the synthesis of many different molecular classes. A tool to aid in catalyst selection, independent of mechanism and reactivity, would therefore be highly desirable. Here, we describe the development of a database for dirhodium(II) catalysts that is based on the principal component analysis of DFT-calculated parameters capturing their steric and electronic properties. This database maps the relevant catalyst space, and may facilitate exploration of the reactivity landscape for any process catalysed by dirhodium(II) complexes. We have shown that one of the principal components of these catalysts correlates with the outcome (e.g. yield, selectivity) of a transformation used in a molecular discovery project. Furthermore, we envisage that this approach will assist the selection of more effective catalyst screening sets, and, hence, the data-led optimisation of a wide range of rhodium-catalysed transformations.

Highly efficient Meerwein-Ponndorf-Verley reductions over a robust zirconium-organoboronic acid hybrid

The Meerwein-Ponndorf-Verley (MPV) reaction is an attractive approach to selectively reduce carbonyl groups, and the design of advanced catalysts is the key for these kinds of interesting reactions. Herein, we fabricated a novel zirconium organoborate using 1,4-benzenediboronic acid (BDB) as the precursor for MPV reduction. The prepared Zr-BDB had excellent catalytic performance for the MPV reduction of various biomass-derived carbonyl compounds (i.e., levulinate esters, aldehydes and ketones). More importantly, the number of borate groups on the ligands significantly affected the catalytic activity of the Zr-organic ligand hybrids, owing to the activation role of borate groups on hydroxyl groups in the hydrogen source. Detailed investigations revealed that the excellent performance of Zr-BDB was contributed by the synergetic effect of Zr4+ and borate. Notably, this is the first work to enhance the activity of Zr-based catalysts in MPV reactions using borate groups.

Selectivity control in inverse electron demand Diels-Alder reaction of o-Quinone methides catalyzed by chiral N,N ‘-Dioxide-Sc(III) complex

The reaction mechanism and origin of asymmetric induction in inverse electron demand Diels-Alder (IEDDA) reaction of ortho-quinone methide (o-QM) and fulvene mediated by chiral N,N’-dioxide-Sc(III) catalyst were rationalized using B3LYP-D3(BJ) functional with def2-TZVP basis set. The uncatalyzed IEDDA reaction was concerted but highly asynchronous with activation barriers of 29.8 similar to 31.8 kcal mol(-1). Good linear relationship between the Hammett substituent constant (sigma(P)) of o-QM and the activation barrier (Delta G(not equal)) of DA reaction was discovered. The secondary orbital interaction (SOI) between the conjugated diene of o-QM and fulvene moiety stabilized the endo-transition state, contributing to high endo-selectivity. The catalytic asymmetric IEDDA reaction occurred via a stepwise mechanism, including the construction of C-beta-C-4 bond, followed by the formation of C-alpha-O-1 bond. The bulky substituents (i.e., adamantyl or triphenylmethyl) in amide moiety of ligand furnished sufficient steric shielding for re-face of diene, inducing the attack of fulvene from si-face in endo-pathway. The substituent at exocyclic methylene of the unsymmetrical fulvene was crucial for the adjustment of E/Z selectivity. The steric repulsion between cyclohexyl group in fulvene and aromatic ring in o-QM raised the destabilizing strain energy (Delta E-strain) at the transition state in Z-configuration, contributing to the predominant E-product.

Construction of Alkali-metal-based Imidazolecarboxylate Coordination Polymers as Efficient Catalysts for Solvent-free Ring-opening polymerization of epsilon-Caprolactone

A series of new alkali-metal-based coordination polymers, [Li(H2IMDC)(H2O)](n) (1), [Na-2(H2IMDC)(2)(H3IMDC)(2)(H2O)(4)](n) (2), and [K(H2IMDC)(H2O)](n) (3), have been constructed under solvothermal conditions by using imidazole-4,5-dicarboxylic acid (H3IMDC) as ligand. The structure of the complexes has been determined by single-crystal X-ray diffraction and further characterized by elemental analyses, IR spectra, powder X-ray diffraction and thermogravimetric analyses. The single crystal X-ray structural studies showed that their structural dimensionalities varying from 1-D zigzag chain, 2-D 4(4)-sql network to 3-D 4,6-connected coordination framework are strongly governed by the ionic radii and coordination geometries of the metal cations. For the first time, the alkali-metal-based coordination polymers were demonstrated to be effective catalysts for the solvent-free ring-opening polymerization (ROP) of epsilon-caprolactone. The catalytic activity of complexes 1-3 depends on the metal cations, increasing in the order Li+ < Na+ < K+.

Environmentally benign approach towards C-S cross-coupling reaction by organo-copper(II) complex

C-S cross-coupling reaction in water giving an excellent yield of the desired C-S coupled product by using a newly developed Bis[2-(4,5-diphenyl-1H-imidazol-2-yl)-4-nitrophenolato] copper(II) dehydrate complex as catalyst. Although it was the first report of the synthesis of such a novel organo-copper complex from our laboratory, its potential catalytic application was not tested so far. Keeping this in mind and based on our anticipation, we developed a greener route for the C-S coupling reaction. The result is very interesting and comprises the subject matter of this report.
