Simple exploration of (S)-(-)-alpha-Hydroxy-gamma-butyrolactone

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 52079-23-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 52079-23-9, in my other articles.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 52079-23-9, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 52079-23-9, Name is (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, molecular formula is C4H6O3

PROCESS FOR THE HYDROGENATION OF ESTERS OF ALPHA-SUBSTITUTED CARBOXYLIC ACIDS

There is provided a process for the hydrogenation of esters of alpha-substituted carboxylic acids which comprises reacting an ester of an alpha-substituted carboxylic acid with hydrogen in the presence of a catalyst under substantially homogeneous supercritical conditions. Preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (1): wherein: R1 and R2are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; and Y is a heteroatom or an optionally substituted heteroatom group. More preferably, the ester of an alpha-substituted is carboxylic acids is an ester of formula (2): wherein: R3 is an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; Q is a functional group; and n 1. Most preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (3): wherein: R3 and R6 are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4 and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; and n 1.
