    Abstract: The reaction of the organolanthanide complexes [.eta..sup.5 --(CH.sub.3).sub.5 C.sub.5 ].sub.2 MCl.sub.2.sup.- Li((C.sub.2 H.sub.5).sub.2 O).sub.2.sup.+, M=La, Nd, Sm, Lu, with LiCH[Si(CH.sub.3).sub.3 ].sub.2 provides a straight-forward route to ether-free and halide- free bis(pentamethylcyclopentadienyl) lanthanide alkyls, (.eta..sup.5 (CH.sub.3).sub.5 C.sub.5).sub.2 MCH--[Si(CH.sub.3).sub.3 ].sub.2. The (.eta..sup.5 (CH.sub.3).sub.5 C.sub.5).sub.2 NdCH[Si(CH.sub.3).sub.3 ].sub.2 complexes react with H.sub.2 under mild conditions to yield the corresponding hydrides [(.eta..sup.5 (CH.sub.3).sub.5 C.sub.5).sub.2 MH].sub.2. These complexes have been found to be extremely active homogeneous olefin polymerization catalysts, as well as catalysts for olefin and acetylene hydrogenation.
