Formation of η-cyclopentadienylpentahydrido(trimethylphosphine)tungsten from cyclopentane, trimethylphosphine, and tungsten atoms

Abstract

Co-condensation of tungsten atoms with cyclopentane and trimethylphosphine gives inter alia, W(η-C₅H₅)(PMe₃)H₅; when cyclopentane is replaced by cyclopentene, W(η-C₅H₅)(PMe₃)₂H₃ and W(η-C₅H₅)(PMe₃)₂(η-C₅H₈)H are formed which on treatment with dihydrogen form the pentahydride W(η-C₅H₅)(PMe₃)H₅.
