Preparation of cis-olefins

Preparation of cis-olefins

A method for preparing a cis-olefin of the formula: R1-CH=CH-R2 by reducing an alkyne of the formula: R1-C IDENTICAL C-R2 with formic acid in the presence of a palladium catalyst. R1 and R2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group,...

description A method for preparing a cis-olefin of the formula: R1-CH=CH-R2 by reducing an alkyne of the formula: R1-C IDENTICAL C-R2 with formic acid in the presence of a palladium catalyst. R1 and R2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group, carboxyl group, cyano group, aliphatic Cl-C20 hydrocarbon group, and phenyl group. The cis-olefin which is a useful intermediate for the synthesis of fine chemicals is selectively produced in high yields.
