A process for preparing an alkyl alkanoate, comprising contacting a an alkene, carbon monoxide (CO), an alcohol, a catalyst and a co-catalyst comprising a Bronsted acid, under alkoxycarbonylation conditions to produce an alkyl alkanoate, wherein the catalyst comprises a metal-organophosphorous ligand complex comprising a ligand of the following formula: wherein X1 - X6 are independently, H, R, Ar, substituted Ar, OR, OAr, CO2R, SiR3, SO3R, SO3H, or fluoro; where R is alkyl or substituted alkyl; where Ar is aryl; and where Y1 - Y8 are independently Ar or substituted Ar, with the proviso that the Y1 - Y8 groups that are bound to the same P atom optionally may be linked with a carbon to carbon bond, CH2, NH, NR, NAr or O. |
