Formation of Unique Platinum-Silyl Complexes by the Reactions of a Zero-valent Platinum Complex with Various Trisilanes

摘要

Trisilanes bearing hydrogen atoms at two more silicon atoms reacted with a zero-valent platinum complex [Pt(dppe)(η~2-C2H4)] to give various types of mononuclear and dinuclear platinum-silyl complexes. Interestingly, in the case of 1,1,2,3,3-pentamethyltrisilane, the Si-Si bond was uniquely activated, resulting in the formation of the diplatinum complex [Pt2-(dppe)2(μ-1,4-SiMe(SiMe2)2SiMe)].
