ABSTRACT:
The invention is a vapor phase process for the preparation of an a-substituted acrylate ester which comprises contacting a haloalkene, wherein the halogen is substituted on an olefinic carbon atom which is further substituted with a C.sub.1-10 alkyl, C.sub.3-10 cycloalkyl, C.sub.6-10 aryl, C.sub.7-10 alkaryl, C.sub.7-10 aralkyl, cyano, trihalomethyl group, with an alcohol or an ether, and carbon monoxide in the presence of a heterogeneous catalyst which comprises palladium, platinum, nickel, ruthenium or rhodium, on a support, under conditions such that an a-substituted acrylate ester and a hydrocarbyl halide is prepared wherein the catalyst productivity is 0.06 g of product per gram of catalyst per hour or greater.
