  • METHOD FOR PREPARING ORGANIC CARBOXYLIC ESTER BY USING COMBINED CATALYST OF ARYL BIDENTATE PHOSPHINE LIGAND
    Publication number: 20220298097
    Abstract: Disclosed is a method for preparing an organic carboxylic ester by using a combined catalyst of an aryl bidentate phosphine ligand. The method includes subjecting a terminal olefin, carbon monoxide, and an alcohol to a hydroesterification reaction in the presence of a combined catalyst of a palladium compound, an aryl bidentate phosphine ligand, and an acidic additive, to generate an organic carboxylic ester having one more carbon atom than the terminal olefin.
