Abstract

A series of cationic gold(I) alpha-diimine complexes of the type [(NHC)Au(alpha-diimine)]X or [(PPh(3))Au(alpha-diimine)]X, where NHC = IPr, alpha-diimine = BIAN-dipp, X = PF(6) (1); X = BF(4) (2); X = SbF(6) (3); NHC = I(t)Bu, alpha-diimine = BIAN-dipp X = PF(6) (4); X = BF(4) (5); NHC = IMes, alpha-diimine = BIAN-dipp, X = PF(6) (6); PPh(3), alpha-diimine = BIAN-dipp, X = PF(6) (7); NHC = IPr, alpha-diimine = DAB-Mes, X = PF(6) (8, 10) bearing an N-heterocyclic carbene (NHC) or a phosphine ligand, have been synthesized and characterized by NMR spectroscopy and single crystal X-ray diffraction. The stability of the new complexes and their catalytic activity for the intermolecular addition of the indole nucleophilic carbon to 1,6-enyne were also investigated.
