A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, molecular formula is C27H37ClN2. In a Article£¬once mentioned of 250285-32-6, Formula: C27H37ClN2
Pd-Catalyzed allylic alkylation of gem- alkyl,aryl-disubstituted allyl reagents with ketones: Diastereoselective construction of vicinal tertiary and quaternary carbon centers
(E)-gem-Alkyl,aryl-disubstituted allyl carbonates can react with ketones under Pd catalysis using a commercially available NHC ligand by suppressing the beta-H elimination. Ketones with alpha-tertiary, beta-quaternary carbon stereocenters were produced in high yields with high regio- and diastereoselectivities. Kinetic resolution of the reaction product via CBS reduction afforded the optically active ketone as well as the alcohol with high enantioselectivity (S-factor = 35). The utility of the methodology was also demonstrated by transformations of the reaction products.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: C27H37ClN2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 250285-32-6, in my other articles.
