| Abstract: | The bissilyl complexes 3 – 6 were synthesized by reactions of the platinum(0) complexes [Pt(η2‐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 η2‐disilene complex. |
