苯没有C-H活化，但四甲基硅烷(TM)的选择性C--Si活化表征了配位的、电子高度饱和的“热”Pt0-络合物2的反应性，该络合物是由顺氢戊基络合物1在室温下通过消除新戊烷而形成的.2可以通过捕获反应检测到；在室温下与TMS反应定量地生成甲基(三甲基硅基)-络合物3，该络合物也是由独立合成的氢化物络合物4分子内重排形成的。
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” Pt 0‐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.
