Rapid, in situ synthesis of bidentate ligands: Chromatography-free generation of catalyst libraries

The parallel synthesis of chiral bidentate ligands and their subsequent use in situ for a catalytic process is described. The ligands thus prepared gave comparable results to those obtained when the ligands were synthesized and purified by conventional means. This includes oxazolines and other compounds of similar complexity, meaning that for the first time these valuable compounds have been brought into the field of combinatorial catalysis.

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 20439-47-8, help many people in the next few years.Quality Control of: (1R,2R)-Cyclohexane-1,2-diamine

Anion-pi Interactions in Hollow Crystals of a Copper(II)-Cyamelurate Coordination Complex

A novel cyamelurate-based copper(II) coordination compound has been designed from a computational approach to show anion-pi interactions between the s-heptazine core and perchlorate anions; therefore, a complex of formula {[Cu(pmta)]3cyam}(ClO4)3 (1) [pmta = N,N,N?,N??,N??-pentamethyl-diethylenetriamine and cyam = cyamelurate ligand] was synthesized. The cationic molecule stabilizes in the solid state with two perchlorate anions one above and the other below the cyamelurate aromatic rings in a polar conformation, crystallizing in the R3c noncentrosymmetric space group with a close cubic packing of the cations. The binding energies were calculated to be ca. -175 kcal/mol for the two species 1:OClO3- and 1:O3ClO-, and the anion-pi contribution could also be calculated, being ca. -10 kcal/mol. The dielectric and magnetic properties were analyzed showing a semiconductor behavior in the temperature range studied (300-458 K) and a weak antiferromagnetic interaction among the three Cu(II) ions. The crystals of 1 show a hollowed hexagonal prismatic morphology, with hollow diameters up to 300 mum. A mechanism based on oriented growth, dissolution, and recrystallization of the outer shell was proposed to explain these hollowed structures.

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.Reference of 3030-47-5, you can also check out more blogs about3030-47-5

Eosinophilic myositis and its medical management in a dog

A six-year male, mongrel dog weighing about 17 kg, presented with complaint of progressive atrophy of temporal, masseter muscles of left side since two months. Clinical examination revealed quidding while taking solid feed and change in voice but vital parameters were found within normal range. Muscle biopsy revealed striated muscle fibre with mild infiltration of polymorphonuclear cells; the inflammatory cells (mainly eosinophilic granulocytes) were distributed between the muscle cells. Based on the history, clinical evaluation and muscle biopsy, diagnosis was made for eosinophilic myositis and treatment was initiated with tab of multivitamin (Thiamine mononitrate 10 mg; riboflavine 10 mg; pyridoxine HCl 3 mg; cyanocobalamin triturate in gelatin eq to cyanocobalamin 15 mcg; nicotinamide 45 mg; calcium pantothenate 50 mg), ascorbic acid 500 mg/day, albendazole @ 400 mg stat, diethylcarbamazine @ 100 mg/day, p.o., for fourteen days along with topically lignocaine gel for application on affected area. After a gap of 7 days, a 14 days course of diethylcarbamazine was repeated with previous dose rate. Uneventful recovery was recorded.

L-Proline transport into renal OK epithelial cells: A second renal proline transport system is induced by amino acid deprivation

Influx of [3H]-l-proline into renal OK cells revealed that basal transport was mediated by the transporter SIT1. When cells were submitted for 8 h to amino acid deprivation, uptake of l-proline was now dominated by a low-affinity system with an apparent K m of 4.4 ¡À 0.6 mM and a V max of 10.2 ¡À 0.6 nmol/mg of protein/min operating in addition to the high-affinity SIT1 system with a K m of 0.12 ¡À 0.01 mM and a V max of 0.28 ¡À 0.04 nmol/mg of protein/min. The low- and high-affinity proline transporting systems were sensitive to inhibitors of JNK and PI-3 kinases, whereas a GSK-3 inhibitor affected only the upregulated transport system. Ion-replacement studies and experiments assessing substrate specificities for both systems provided strong evidence that SNAT2, that showed two- to threefold increased mRNA levels, is the responsible transporter mediating the increased proline influx under conditions of amino acid deprivation.

Intermediate pyrolysis of Acacia cincinnata and Acacia holosericea species for bio-oil and biochar production

Ever-increasing energy requirements coupled with the desire to cope with global warming have motivated researchers to look for alternative energy resources. Lignocellulosic biomass is an abundant renewable energy resource which can be exploited to reduce the dependency on fossil fuel resources. Acacia cincinnata and Acacia holosericea are fast-growing tree species which produce large quantities of biomass within short span of time and does not require major agricultural inputs to grow. This study is aimed at the intermediate pyrolysis process of Acacia cincinnata and Acacia holosericea species to produce biofuels such as bio-oil, biochar and gaseous product. Mass balance was done to calculate the yields of different products along with the characterisation of bio-oil and biochar produced. Experiments were carried out in a fixed-bed reactor at the pyrolysis temperature of 500 C, heating rate of 25 C/min and nitrogen gas flowrate of 100 cm3/min for the biomass feedstock having particle size between 0.5 and 1 mm. Comprehensive thermochemical characterisation of biomass samples was carried out prior to pyrolysis experiments. The chemical composition of bio-oil samples produced was determined using Gas Chromatography-Mass Spectroscopy (GC?MS) technique. Ultimate analysis, calorific values, pH values and the ash contents in the bio-oil samples were also determined. Bio-oil produced were reported to be complex mixtures of heterocyclic and phenolic compounds resulting from the thermal degradation of basic components of biomass with the calorific values obtained in the range of 23.46?30.65 MJ/kg. Biochar samples produced in the study were characterised with the help of ultimate analysis, FTIR analysis, calorific values, pH values and SEM and EDX analysis. Properties of biochars indicated suitability for energy as well as other applications such as soil remediation and adsorption purposes. Study revealed a decent potential of Acacia cincinnata and Acacia holosericea species as biofuels resources.

Robust bifunctional aluminium-salen catalysts for the preparation of cyclic carbonates from carbon dioxide and epoxides

Two new one-component aluminium-based catalysts for the reaction between epoxides and carbon dioxide have been prepared. The catalysts are composed of aluminium-salen chloride complexes with trialkylammonium groups directly attached to the aromatic rings of the salen ligand. With terminal epoxides, the catalysts induced the formation of cyclic carbonates under mild reaction conditions (25-35 C; 1-10 bar carbon dioxide pressure). However, with cyclohexene oxide under the same reaction conditions, the same catalysts induced the formation of polycarbonate. The catalysts could be recovered from the reaction mixture and reused.

Synthesis and properties of phosphorescent iridium(iii) complexes of delocalized ligands

New Ir(iii) complexes involving N,C-chelating difluorophenyl-pyridine (dfppy) or dibenzo[a,c]phenazine (dbpz) ligands along with either N,N-bound 5-ethynyl-2,2?-bipyridine (e-bpy) or CO + Cl co-ligands have been obtained as [Ir(dfppy)2(e-bpy)]PF6, [Ir(dbpz)2(e-bpy)] PF6 and cis-[Ir(dbpz)2(Cl)(CO)]. A single-crystal X-ray diffraction study of cis-[Ir(dbpz)2(CO)Cl] has shown the Ir(iii) centre to adopt a distorted octahedral coordination geometry with cis-CO/Cl and trans-N,N configurations. Pronounced pi-pi stacking interactions involving different dibenzo[a,c]phenazine units are evident. Electronic absorption and luminescence spectroscopy at 298 K and 77 K, along with cyclic voltammetry were used to study the three complexes. Excited state lifetimes varied from 1.4 to 2.9 mus at rt with quantum yields ranging from 10.2 to 0.7%. With 5-ethynyl-2,2?-bipyridine in the first coordination sphere, the lowest emitting state is that associated with the MLCT band, whereas in the bis-phenazine case the emission is ligand-centred. Importantly, the emission wavelength can be tuned from 552 to 640 nm by changing the conjugation length of the N,C ligand. The Royal Society of Chemistry 2013.

Facile synthesis and spectroscopic elucidation of 4,11-bis(dehydroxy)-bipolaroamide

A new diketopiperazine was formed by facile condensation of the artificial 2-indoline carboxylic acid. This highly crystalline compound was characterized by NMR-spectroscopy as well as X-ray crystallography. Spectroscopic data of the new pentacyclic diketopiperazine revealed further evidence that the phosphite-promoted coupling used is free of racemization or inversion. These stereochemical results are important for this advanced reaction and may lead to a key step in the total synthesis of many natural products. The dimerized 2-indoline carboxylic acid described herein was chosen to be a model system for structure and reaction studies on route to the favored rostratines.
