Mono(cyclopentadienyl)molybdenum chemistry: hydrido-, halogeno-, allylic, and butadiene derivatives of [1,2-bis(diphenylphosphino)ethane](η-cyclopentadienyl)molybdenum and related compounds

Abstract

The new compounds [Mo(η-C₅H₅)₂L₂][PF₆]₂, [Mo(η-C₅H₅)(η³-C₅H₇)(dppe)], [Mo(η-C₅H₅)L₂Cl₃], [Mo(η-C₅H₅)(dppe)H₃], [Mo(η-C₅H₅)(dppe) Br₃]·C₆H₅Me, [Mo(η-C₅H₅)₂(NCMe)₂][PF₆]₂, [Mo(η-C₅H₅)₂(dppm)H][PF₆], [Mo(η-C₅H₅)(dppm)Cl][PF₆]·0.5CH₂Cl₂, and [Mo(η-C₅H₅)(exo-H-C₅H₅)(dppm)][PF₆]·CH₂Cl₂[L₂= 1,2-bis (diphenylphosphino)ethane (dppe) or bis(diphenylphosphino)methane (dppm)] have been prepared. The trihydride [Mo(η-C₅H₅)(dppe)H₃] reacts with butadiene giving [Mo(η-C₅H₅)(dppe)(η³-C₃H₄Me)].
