Metal-free nucleophilic activation of a B-B bond has been exploited in the development of a highly efficient method for conjugate additions of commercially available bis(pinacolato)diboron to cyclic or acyclic alpha,beta-unsaturated carbonyls. The reactions are readily catalyzed by a simple N-heterocyclic
