PROCESS FOR THE PREPARATION OF AN (AR)ALKENE CARBOXYLIC ACID

摘要

A process for the preparation of an (ar)alkene carboxylic acid is disclosed wherein an (ar)alkene is reacted with a carbonyl compound having at least one hydrogen atom linked to the alpha -carbon atom in the presence of a polyvalent manganese compound which is at least trivalent and a bivalent copper compound. The presence of the latter compound will minimize or prevent undesired by-products of the reaction.
