first utility of praseodymium as a mediating metal in the Barbier reaction of carbonylcompounds with allyl halides was reported in this paper. In contrast to the traditional metal-mediated or catalyzed Barbier reactions, exclusive α-adducts were obtained in this one-pot reaction with a broad scope of substrates and feasible reaction conditions.
The electroreduction of a catalytic amount of ZnBr2 in acetonitrile provided a active Zn*, able to catalyze the reductive coupling of allyl bromides and chlorides with carbonyl compounds with high regioselectivity. Substituted α-methylene γ-lactones were obtained from functionalized allyl derivatives.

A mild, catalytic method for the intermolecular reductive coupling of feedstock dienes and styrenes with ketones and imines is reported. Applications of this straightforward approach include the efficient synthesis of drug molecules and site-selective late-stage functionalisation.
