A novel process for the removal of an allylic group in an allylic ester or of an allylic-oxycarbonyl group in an allylic carbonate or carbamate is disclosed allowing very mild reaction conditions. The process is effected by reacting a solution of the allylic ester, carbonate or carbamate in an organic, aprotic solvent in the presence of a catalytic amount of an organic-soluble palladium complex having a coordinating phosphine ligand with a carboxylic acid having from five to eighteen carbon atoms or an alkali metal salt thereof or with sodiumcyanoborohydride or sodiumborohydride.

An improved synthetic process for the removal of an allyl group in an allylic ester or an allyloxycarbonyl group in an allylic carbonate or carbamate by reaction with 2-ethylhexanoic acid or an alkali metal salt thereof and a catalytic amount of an organic-soluble palladium complex is disclosed herein.
