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.
Claims16
A method for preparing an organic carboxylic ester, comprising the step of:
- subjecting a terminal olefin, carbon monoxide, and an alcohol to a hydroesterification reaction in an organic solvent in the presence of a combined catalyst to generate an organic carboxylic ester having one more carbon atom than the terminal olefin,
- wherein the combined catalyst comprises a palladium compound, an aryl bidentate phosphine ligand, and an acidic additive;
- and
- the aryl bidentate phosphine ligand has a structural formula selected from the group consisting of the following formulas a, b, c, e, f, g, h, i, j, m, r, u, w, and x:
