ETUDE DE LA REGIOSELECTIVITE DE LA SUBSTITUTION DES CARBANIONS PAR DES DERIVATIVES ALLIQUES CATALYSEE AU PALLADIUM. OBTENTION SELECTIVE DE COMPOSES A CARBONE QUATERNAIRE

The influence of the leaving groups, carbanions and ligands on ?-allylpalladium has been investigated in the substitution of primary or tertiary terpene derivatives.Conditions have been found under which the substitution takes place essentially at one or the other end of the allylic system.This provides a new and convenient way to obtain compounds with quaternary carbon atoms, which has been exemplified by the synthesis of 3,3-dimethyl-4-pentenenitrile.
