Method for the preparation of alkenyl esters of carboxylic acids

摘要

A novel and effective catalyst system is provided for application in the preparation of alkenyl esters of carboxylic acids by transesterification reaction. The catalyst system consists of a palladium compound as the main ingredient and a cocatalyst formed of an alkali metal compound and a copper compound, at least one of which is a halide. The catalyst ingredients are adsorbed on a solid catalyst carrier, so that repeated use of the combined catalyst or a continuous operation of the reaction can easily be facilitated.
