文摘

A series of cationic gold(I) 伪-diimine complexes of the type [(NHC)Au(伪-diimine)]X or [(PPh₃)Au(伪-diimine)]X, where NHC = IPr, 伪-diimine = BIAN-dipp, X = PF₆ (1); X = BF₄ (2); X = SbF₆ (3); NHC = I^tBu, 伪-diimine = BIAN-dipp, X = PF₆ (4); X = BF₄ (5); NHC = IMes, 伪-diimine = BIAN-dipp, X = PF₆ (6); PPh₃, 伪-diimine = BIAN-dipp, X = PF₆ (7); NHC = IPr, 伪-diimine = DAB-Mes, X = PF₆ (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.
