摘要：

Multiple C-C coupling of isocyanides has been demonstrated by the ambient-pressure reactions of CNMe with Cp2M(N(CMe3)CC(=NCMe3)CH2SiMe2CH2) and the high-pressure reactions of CNCMe3 with CP2M(CH2SiMe2CH2), which afford Cp2M(N(Me)C-C(=NCMe3)C(=NCMe3)CH2SiMe2CH2) and Cp2M(N-(CMe3)C(=C=NCMe3)C(=NCMe3)CH2SiMe2CH2) (M = Zr, Hf), respectively.
