Chemical Research Letters, April 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 28562-53-0, Name is 4-Acetoxy-2-azetidinone, molecular formula is C5H7NO3, HPLC of Formula: https://www.ambeed.com/products/28562-53-0.html, belongs to isothiazole compound, is a common compound. In a patnet, author is Crosby, J, once mentioned the new application about 28562-53-0.
Thermolysis of 1,4,2-dithiazol-5-ones in the presence of dimethyl acetylenedicarboxylate yielded dimethyl isothiazole-4,5-dicarboxylates, together with sulfur, carbon oxysulfide and nitriles. The proposed mechanism involves initial expulsion of carbon oxysulfide, followed by 1,3-dipolar cycloaddition of the resulting nitrile sulfide to the alkyne. The corresponding reaction of dithiazolone 3b with ethyl propiolate afforded a ca 1: 1.2 regioisomeric mixture of ethyl 3-phenylisothiazole-4- and 5-carboxylates, similar to that found for benzonitrile sulfide generated from 1,3,4-oxathiazol-2-one 1b.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
