Preparation of α-unsaturated carboxylic esters and amides from 1,2-dihaloalkanes by carbonylation |
| abstract |
The invention is a process for preparing α-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 α-unsaturated carboxylic esters or amides prepared by the addition of a free radical inhibitor capable of improving catalyst lifetime to the reaction mixture. |
