ABSTRACT:
The invention is a process for preparing .alpha.-unsaturated carboxylic esters or amides comprising contacting a 1,2-dihaloalkane, an alcohol or amine, and carbon monoxide, in the presence of a catalytic amount of a group VIII metal at elevated temperatures and pressures. The invention further includes preventing the .alpha.-unsaturated carboxylic esters or amides prepared by the addition of a free radical inhibitor capable of improving catalyst lifetime to the reaction mixture.
