the general formula [Au2(S–C≡C–spacer–C≡C–S)L2] (L = monophosphanes; spacer = none, 1,4-C6H4, 1,3-C6H4, 2,7-C15H12 and 3,5-C7H7N). The dinuclear structure was confirmed by X-ray diffraction studies of the complexes (PPN)2[Au2(S–C≡C–C≡C–S)(C6F5)2] and [Au23,5-(S–C≡C)2–C7H7N}(PPh3)2] PPN = bis(triphenylphosphane)iminium}. The use of diphosphanes gives complexes with higher nuclearity and cyclic structures
双(1,2,3-噻二唑)在强碱存在下的原位裂解得到双(炔硫醇),其提供双(炔硫醇)金(I)衍生物,通式为 [Au2(S–C ≡C–spacer–C≡C–S)L2](L = 单膦;spacer = 无、1,4-C6H4、1,3-C6H4、2,7-C15H12 和 3,5-C7H7N)。双核结构通过配合物 (PPN)2[Au2(S–C≡C–C≡C–S)(C6F5)2] 和 [Au23,5-(S–C ≡C)2–C7H7N}(PPh3)2] PPN = 双(三苯基膦)亚胺}。双膦的使用产生具有更高核数和环状结构的复合物。(© Wiley-VCH Verlag GmbH & Co.
