Abstract: A catalytic process for the methoxycarbonylation of olefins where formic acid is the CO source. The process includes the steps of forming a reaction mixture where methanol and formic acid are added at a volume ratio in the range from 1.55:0.45 to 1.1:09. The methanol-formic acid ratio enhances both the rate of conversion and methyl ester yield ether produced. The catalysts used is a palladium/benzene-base diphosphine ligand complex.
