摘要

A highly efficient cross-coupling of diarylborinic acids and anhydrides with aryl chlorides and bromides has been effected by using a palladium catalyst system co-supported by a strong σ- donor N-heterocyclic carbene (NHC), N, N′-bis (2, 6-diisopropylphenyl) imidazol-2-ylidene, and a strong π-acceptor phosphite, triphenylphosphite, in tert-BuOH in the present of K3PO4· 3H2O. Unsymmetrical biaryls with a variety of functional groups could be obtained ...
