摘要：

The complexes [PtMe2((t)Bu(2)bpy)], 1a, (t)Bu(2)bpy = 4,4'-di-tert butyl-2,2'-bipyridine, and [PtMe(ppy)PPh3], 1b, ppy = deprotonated 2-phenylpyridine, react very easily with BiX3 (X = Cl, Br, or I) to give [PtMe2(X)(2) ((t)Bu(2)bpy)] (2a, X = Cl; 3a, X = Br; 4a, X = I) and [PtMe(X)(2)(ppy)PPh3] (2b, X = Cl; 3b, X = Br; 4b, X = I), respectively. In these oxidative addition reactions, BiX3 reagent can be used as halide source instead of hazardous reagents X-2. The dihaloplatinum(IV) complexes are characterized using NMR spectroscopy and the structures of complexes 4a and 3b are further identified by X-ray crystallography. Structures of Pt(IV) complexes are investigated using DFT calculations at B3LYP level of theory. (C) 2014 Elsevier Ltd. All rights reserved.
