In the chiral Co(III)(salen)-catalysed HKR of racemic epoxides, in the presence of ionic liquids, Co(II)(salen) complex is oxidised without acetic acid to catalytically active Co(III)(salen) complex during reaction and, moreover, this oxidation state is stabilised against reduction to Co(II) complex which enables the reuse of the recovered catalyst for consecutive reactions without extra reoxidation.

The infrared and vibrational circular dichroism (VCD) spectra of six chiral oxorhenium(V) complexes, bearing a hydrotris(1-pyrazolyl)borate (Tp) ligand, have been investigated. These complexes are promising candidates for observation of parity violation (symmetry breaking due to the weak nuclear force). New chiral oxorhenium complexes have been synthesized, namely, [TpReO(eta 2-O(CH3)CH2CH2O-O,O)] (4a and 4b) diastereomers and [TpReO(eta2-N(CH3)CH 2CH2O-N,O)] (5) and [TpReO(eta2-N(tBu)CH 2CH2O-N,O)] (6) enantiomers. All compounds could be obtained in enantiomerically pure form by using either column chromatography or HPLC over chiral columns. VCD spectroscopy of these compounds and of [TpReO(eta2-N(CH3)CH(CH3)CH(Ph)O-N,O)] (2) and [TpReO(eta2-N(CH2)3CHCO2-N,O)] (3) (with chiral bidentate ligands derived, respectively, from ephedrine and proline) were studied. This allowed the absolute configuration determination of all compounds together with their conformational analysis, by comparing calculated and experimental spectra. This is the first VCD study of rhenium complexes which further demonstrates the applicability of VCD spectroscopy in determining the chirality of inorganic complexes.

For the role of monomeric metaphosphate and the nature of the transition states in the alcoholysis of phosphoric monoesters to be examined, phenyl <(R)-16O,17O,18O>phosphate and 2,4-dinitrophenyl <(R)-16O,17O,18O>phosphate have been synthesized and the stereochemical course of the methanolysis of phenyl phosphate monoanion and of dinitrophenyl phosphate dianion has been evaluated. <(R)-16O,17O,18O>Phosphocreatine has also been synthesized and the stereochemical course of the methanolysis of this molecule determined.In each case, complete inversion of configuration at phosphorus is observed.It is clear that metaphosphate, if it exists as a true intermediate in these reactions in protic solvent, does not leave the solvent cage in which it is generated.Indeed, product formation occurs more rapidly than rotation of the putative metaphosphate intermediate.These displacements must therefore occur by preassociative mechanisms in which there may be some assistance from the incoming nucleophile.The present results do not allow a distinction to be made between a “preassociative concerted” path (that is, an SN2-like displacement via a very loose transition state) and a “preassociative stepwise” path via a metaphosphate intermediate of very short lifetime.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 4254-15-3 is helpful to your research. Related Products of 4254-15-3

The present invention includes a process for enantioselective preparation of a non-racemic compound, which is either usable as a fragrance or flavor component or is convertible to a fragrance or flavor component by one or more additional reaction steps. The process includes the step of contacting either a substrate capable of forming a non-racemic compound by an enantioselective reaction and a co-reactant in the presence of a non-racemic catalyst, or a non-racemic or enantiopure substrate and a co-reactant, optionally in the presence of a racemic or non-racemic catalyst. The contacting is carried out at a temperature and length of time that is sufficient to produce the non-racemic compound with high optical purity. The process is used in stereoselective preparation of enantiomerically enriched intermediates useful in the preparation of non-racemic, chiral flavor and fragrance components.

Vibrational Circular Dichroism combined with FTIR spectroscopy (VCD-IR) is demonstrated as a viable tool for the in situ measurement of enantiomeric excess during asymmetric catalytic transformations. Employing the Jacobsen (salen)Co-catalyzed hydrolytic kinetic resolution of racemic epoxides as a proof-of-concept case study, methodology is developed to monitor the enantiomeric excess of the epoxide substrate as a function of conversion of the limiting reactant, water. Comparison of results for monomeric and oligomeric catalysts probes the molecularity of the catalyst by investigating nonlinear effects in catalyst enantiopurity. These results are in excellent agreement with previous mechanistic investigations of this reaction based on kinetic measurements and computational studies.
