Abstract

Addition of an excess of t-butyl isocyanide to solid Mo₂ (O₂ CCF₃)₄ or Mo₂ - (O₂ CMe)₄ gives (t-BuNC)₅ Mo(O₂ CCF₃)₂ or (t-BuNC)₄ Mo(O₂ CMe)₂, respectively. The quadruple bond in K₄Mo₂ Cl₈ or C1₄Mo₂ (n-Bu₃P)₄ also can be cleaved by an excess of t-butyl isocyanide to yield (t-BuNC)₅ MoCl₂. The anionic ligands can be exchanged with ammonium hexafluorophosphate in presence of excess t-BuNC to give the known [(t-BuNC)₇ Mo] [PF₆ ]₂ · t-Butyl isocyanide also cleaves the quadruple metalmetal bond in Re₂ (O₂ CMe)₄ C1₂ to give (t-BuNC)₅ ReCl.
