摘要

The reactions of R₂PP(SiMe₃)Li (R = ^tBu, ⁱPr₂N) with [Cp₂MoCl₂] yield terminal phosphanylphosphido complexes formally via the insertion of the phosphinidene P-atom into the CH bond of a cyclopentadienyl ring and the migration of the hydrogen atom or SiMe₃ moiety to the molybdenum centre. Solid state structures of [Cp(C₅H₄PP^tBu₂)MoH], [Cp(C₅H₄PP^tBu₂)Mo(SiMe₃)] and [Cp{C₅H₄PP(NⁱPr₂)₂}Mo(SiMe₃)] were established by single crystal X-ray diffraction. The proposed reaction path is supported by the results of NMR studies and DFT calculations.
