Novel Platinum Complexes Enable Selective C‐H and C‐Si Activation of Tetramethylsilane at Room Temperature

Abstract

No CH activation of benzene, but a selective CSi activation of tetramethylsilane (TMS) characterizes the reactivity of the coordinative and electronically highly saturated, “hot” Pt0-complex 2, which is formed from the cis-hydridoneopentyl complex 1 at room temperature by elimination of neopentane. 2 can be detected by trapping reactions; reaction with TMS at room temperature leads quantitatively to the methyl(trimethylsilyl)-complex 3, which is also formed by intramolecular rearrangement of the independently synthesized hydride complex 4.
