Arene molybdenum chemistry: the preparation of some arene molybdenum π-allyl derivatives and a unique diprotonation reaction of benzenetristertiaryphosphinemolybdenum derivatives

Abstract

New arene–molybdenum derivatives are described of stoicheiometry PhRMo(π-C₃H₅)Y [Y =π-C₃H₅, π-C₃H₄Me, π-C₃H₄(CH₂·CN), π-C₃H₄(CH₂·OMe), MeCO₂, NH₂·CH₂·CO₂, or NH₂·CH₂·CH₂S; R = H or Me] and of stoicheiometry [PhRMo(π-C₃H₅)L₂]+PF₆ ^–(or BF₄ ^–)[L₂= butadiene, MeS·CH₂·CH₂·SMe, bipyridyl, ethylene-diamine, or Ph₂P·CH₂·CH₂·PPh₂]; the dication [C₆H₆Mo(Me₂PhP)₃H₂]₂ ²⁺ formed by addition of two protons to the neutral compound C₆H₆Mo(Me₂PhP)₃.
