alpha-Regioselective Barbier Reaction of Carbonyl Compounds and Allyl Halides Mediated by Praseodymium

摘要

The first utility of praseodymium as a mediating metal in the Barbier reaction of carbonyl compounds with allyl halides was reported in this paper. In contrast to the traditional metal-mediated or catalyzed Barbier reactions, exclusive a adducts were obtained in this one-pot reaction with a broad scope of substrates and feasible reaction conditions.
