Selectivity in nickel-catalyzed rearrangements of cyclopropylen-ynes.

Gang Zuo1, Janis Louie.   

Abstract

The Ni/NHC-catalyzed rearrangement of cyclopropylen-ynes is described. Two different heterocycles, cyclopentane- or cycloheptene-based, were obtained. However, by employing ItBu as the NHC ligand, cyclopentane products were obtained selectively under mild conditions.
