摘要:
Palladium(II) complexes of the general formulae [PdCl2((PN)-N-boolean AND)] and [Pd(Me)Cl((PN)-N-boolean AND)] were obtained from bidentate ligands bearing phosphine and imine donor groups. The complexes were shown to be highly active catalysts for the Suzuki-Miyaura cross-coupling reaction. The complexes are tolerant of a wide variety of reaction conditions such as solvent, choice of base as well as substituents on both arylboronic acids and aryl halides. (C) 2012 Elsevier B.V.
