摘要：

The bissilyl complexes 3-6 were synthesized by reactions of the platinum(0) complexes [Pt((2)-C2H4)(diphos)] (1: diphos = dppe; 2: diphos = dcpe) with the disilanes 1, 1,2, 2-tetramethyldisilane and 1, 1,2, 2-tetraphenyldisilane via Si-Si bond activation. The molecular structures of 4 and 5 in the solid state are reported. The reaction of 2 with HPh2SiSiPh2H led to the immediate formation of the hydrido disilanyl complex [Pt(H)(SiPh2SiPh2H)(dcpe)] (7), which converts slowly into the bissilyl complex [Pt(SiHPh2)(2)(dcpe)] (6). The latter was reported before to be a (2)-disilene complex.
