摘要：
The pyridine-carboxamide ligand PhNHC(=O)-2-C5H4N reacts with Na+[AuCl4](-) either by cation exchange, to give [PhNHC(=O)-2-C5H4NH][AuCl4], or by ligand substitution to give [AuCl2(kappa(2)-N,N'-PhNC(=O)-2-C5H4N)]. Similar reactions with bis(pyridine-carboxamide) ligands gave complexes [AuCl2(kappa(2)-N,N'-RNC(=O)-2-C5H4N)], with R = (CH2)(3)NHC(=O)-2-C5H4N or 2-C6H4NHC (=O)-2-C5H4N, in which the ligands are bidentate, but no complexes with tetradentate ligands could be isolated. The complex [AuCl2(kappa(2)-N,N'-PhNC(=O)-2-C5H4N)] in methanol solution is an efficient catalyst for oxidative cyanation of PhNMe2 to give PhMeNCH2CN, and it is proposed that the catalysis involves gold(I), gold(II) and gold(III) intermediates.
