Co-condensation of atoms of tungsten rhenium, and chromium with a mixture of cyclohexane and trimethylphosphine causes activation of the cyclohexane giving the compounds W(η-C6H8)(PMe3)2H4, W(η-C6H8)(PMe3)3H2, W(η-C6H6)(PMe3)2H2, W(PMe3)4H4, Re(η-C6H6)(PMe3)2H, and Cr(η-C6H6)(PMe3)3 respectively; when tungstenatoms react with a 3 : 1 mixture of cyclohexane and perdeuteriocyclohexane, together with
钨rh和铬的原子与环己烷和三甲基膦的混合物共缩合会导致环己烷活化,从而得到化合物W(η- C6 H 8)(PMe 3)2 H 4,W(η- C6 H 8)(PMe 3)3 H 2,W(η- C6 H 6)(PMe 3)2 H 2,W(PMe 3)4 H 4,Re(η- C6 H 6)(PMe 3)2 H和Cr(η-C6 H 6)(PMe 3) 3;当钨原子与环己烷和全氘代环己烷的3:1混合物以及PMe 3反应时,则不存在混合的H–D钨产物,这表明C–H活化过程是分子内的。
