A nucleophilically promoted cyclisation of a phosphavinylidene
Abstract
The reaction of the phosphavinylidene [Mo(CO)2{σ-PC(SiMe3)2}(η-C5H5)] with Me– or H–, followed by treatment with MeOH or Mel, affords [(η-C5H5)(CO)2[graphic omitted]R1R2](R1, R2= H, Me); the corresponding reaction with MeO– is more complex.
