A method for preparing a cis-olefin of the formula :
R1-CH=CH-R2 by reducing an alkyne of the formula:
R1-C≡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 CI-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.
一种制备式......的顺式烯烃的方法
R1-CH=CH-R2 的顺式烯烃的制备方法:
R1-C≡C-R2 在钯催化剂存在下用甲酸还原。R1 和 R2 独立地选自氢原子、酯基、取代的硅烷基、羧基、氰基、脂肪族 CI-C20 烃基和苯基组成的组。这种顺式烯烃是合成精细化学品的有用中间体,可选择性地以高产率生产。
