13C NMR, alone or in combination with 1H NMR, allows the assignment of the absolute configuration of chiral alcohols, amines, carboxylic acids, thiols, cyanohydrins, sec,sec-diols and sec,sec-aminoalcohols, derivatized with appropriate chiral auxiliaries. This extends the assignment possibilities of NMR to fully deuterated and to nonproton containing compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C14H15NO, you can also check out more blogs about23364-44-5

Artificial photosynthesis is envisioned as a promising strategy to convert sunlight, a practically unlimited and sustainable source of energy, into chemical fuels. In this scheme, the oxidation of water molecules is necessary to provide the electrons than will be employed in the synthesis of chemical fuels. Water oxidation is a particularly challenging reaction because it is a thermodynamically uphill multielectronic process with large activation barriers, but it is key for the realization of artificial photosynthesis because water is the only earth abundant molecule that can provide electrons in a massive and sustainable manner. Therefore, catalysts are needed for eluding the large intrinsic kinetic barriers of the reaction. In nature, water oxidation is catalyzed by a Mn tetrameric species, which enables O?O formation under the inherent mild physiological conditions trough a putative high valent manganese oxo species. Taking natural water oxidation as model, molecular catalysts operating under homogeneous conditions have been explored with the objective of providing basic understanding at molecular scale of the factors that govern this reaction, which eventually will receive utility in the design of efficient water oxidation devices. Traditionally, water oxidation has been studied with ruthenium and manganese based systems, but more recently attention has been shifted toward catalysts based on iridium and first row transition metals: the former due to their extraordinary performance and the latter because of their favorable cost, availability and environmental impact when compared with second and third row transition metals. The topic has been very actively explored and important lessons have been gained. Catalysts based on first row transition metals poise specific problems in terms of stability because generally their metal-ligand bonds are labile and because reaching their high oxidation states require high oxidation potentials. Consequently, high valent states of these metals are exceedingly reactive, readily prone to engage in oxidative decomposition paths. Catalyst design is crucial for circumventing these problems and has enabled the discovery of extraordinarily reactive yet reasonably stable catalysts, comparable to the best examples based on second and third row transition metals. The following chapter reviews key contributions to the field. The manuscript does not intend to be comprehensive, but instead, selected and in our opinion representative examples are discussed.

Compound [Co(4-terpyridone)2](CF3SO3) 2·1H2O, where 4-terpyridone is 2,6-bis(2-pyridyl)- 4(1H)-pyridone, forms two polymorphs. Polymorph 1 displays a continuous spin conversion in the temperature region 300-120 K while polymorph 2 shows, on cooling, the onset of a continuous high-spin (HS) to low-spin (LS) conversion interrupted by an abrupt “reverse” spin transition in the temperature region 217-203 K. The formed unstable HS intermediate phase (IP) undergoes a strong cooperative “normal” spin transition characterised by a hysteresis loop 33 K wide. The structural data give support for a crystallographic phase transition, which takes place concomitantly with the “reverse” spin state transition. copy; The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.

This article summarizes the basic concepts and synthetic strategies leading to various types of supramolecular polymers with chelated units, including linear, branched, cross-linked, and heterometallic polymers. Particular attention is paid to such new synthetic approaches to supramolecular polymers as hierarchical and orthogonal self-assembly based on a combination of metal?ligand interaction with hydrogen bonds and host?guest interactions. Metallosupramolecular polyelectrolytes, supramolecular polymer gels, self-assembled metallosupramolecular monolayers, and supramolecular metal chelate dendrimers are analyzed. The stimuli-responsive, self-healing, and shape memory supramolecular polymers with chelated units are considered. The bibliography includes articles published over the past five years.

The ligand H2sal-cys (I) derived from salicylaldehyde and Lcysteine has been covalently bonded to chloromethylated polystyrene cross-linked with 5% divinylbenzene. Upon treatment with [VO(acac)2] in dimethylformamide (DMF) the polystyrene-bound ligand PS-H2sal-cys (II) gave the oxidovanadium(IV) complex, PS-[VO(sal-cys)·DMF] (1). The corresponding neat complex, [VO(sal-eta)]2 (2), has also been prepared similarly in methanol. These complexes have been characterised by IR, electronic, EPR spectroscopic studies, magnetic susceptibility measurements and thermal as well as scanning electron micrographs studies. Complex [VO-(sal-eta)]2 exhibits a medium intensity band at 980 cm -1 in the IR spectrum due to nu(V=O) stretch. Broad features of the EPR spectrum for the neat complex along with magnetic susceptibility studies suggest the presence of antiferromagnetic exchange interaction between two vanadium centers in close proximity. Both complexes catalyze the oxidative amination of styrene, in mild basic conditions, with secondary amines (diethylamine, imidazole, and benzimidazole) and gave a mixture of two aminated products in good yields. Amongst the two aminated products, the anti-Markovnikov product is favored over the Markovnikov one due to the steric hindrance posed by the secondary amines. The polymeranchored heterogeneous catalyst is free from leaching during catalytic action and recyclable. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

An electrochemical synthesis method for the selective N1-acylation of indazoles has been developed. This “anion pool” approach electrochemically reduces indazole molecules generating indazole anions and H2. Acid anhydrides are then introduced to the solution resulting in selective acylation of the N1-position of the indazoles. This procedure can also be applied to the acylation of benzimidazoles and indoles. The reaction can also be performed using a 9 V battery without loss of reaction efficiency.

The inclusional process of decyltrimethylammonium bromide (DTAB) into the cavity of beta-cyclodextrin (beta-CD) has been studied by measuring speed of sound (u) of aqueous solutions of DTAB in the presence of various constant concentrations of beta-cyclodextrin at 298.15 K.The predominant complex formed has a stoichiometry of 1:1.The apparent critical micellar concentrations, cmc* (the cmc for the system DTAB + beta-CD + H2O), is found to increase upon the addition of cyclodextrin, while the concentration of free surfactant available for the micellization process in the presence of beta-CD (f) increases slightly.The binding or association constant of the complexation equilibrium is evaluated from u measurements by using a nonlinear regression method.The resulting K value is analyzed and compared with those given by other researchers and the discrepancies are discussed.
