ORGANOPALLADIQUES ISSUS DES ESTERS D'ALCOOLS α-ALLENIQUES: REACTIONS AVEC LES ANIONS DELOCALISES.
The esters of α-allenic alcohols, and particularly the phosphates, react in the presence of catalytic amounts of a palladium(O) complex with the anions of β-diesters, β-ketoesters and α-phenylsulfonylesters, leading by a direct substitution to β-difunctionalized allenes.This reaction can be applied to the fast obtention of an intermediate of the synthesis of the pheromone of dried bean beetle.
