使用配位的H分子作为离开基团以生成不饱和的反应络合物已被证明是一种很好的进入乙烯加氢的新路线。1最初提供16E-络合物2，它立即与C2H4配位形成3，这是催化循环的第一个物种。在C2H4过量的情况下，二乙烯络合物4(以BF盐的形式)可以作为稳定的最终产物分离出来。
The use of a coordinated H2molecule as leaving groupin order to generate an unsaturated reactive complex has proven to be an excellent entry to a new route for ethylene hydrogenation.1initially affords the 16e‐complex2, which immediately coordinates C2H4with formation of3, the first species of a catalytic cycle. With an excess of C2H4, the bisethylene complex4(as BF salt) can be isolated as stable end product.
