Abstract
Process for the preparation of an ester of a 3-aryl-substituted acrylic acid by reacting (a) an aromatic hydrocarbon having one aliphatic carbon atom less than said 3-aryl-substituted acrylic acid and carrying a 1-alkenyl substituent, (b) carbon monoxide and (c) an alcohol in the presence of a Group VIII noble metal or a compound thereof, a quinone and a redox agent.

A process for the preparation of an ester of a 3-aryl-substituted acrylic acid which comprises reacting (a) an aromatic hydrocarbon containing a 1-alkenyl group with at least one hydrogen atom in beta-position, (b) carbon monoxide and (c) an alcohol, at a partial pressure of carbon monoxide below about 10 bar, in the presence of:
- (1) a noble metal selected from the group consisting of Group VIII of the Periodic Table of the Elements, a compound of a Group VIII metal, and mixtures thereof,
- (2) a quinone, and
- (3) a redox agent,
- and isolating said ester from the reaction mixture thus obtained.
