The reaction of the organolanthanide complexes [ eta 5-(CH3)5C5]2MCl2-Li((C2H5)2O)2+, M=La, Nd, Sm, Lu, with LiCH[Si(CH3)3]2 provides a straight-forward route to ether-free and halide-free bis(pentamethylcyclopentadienyl) lanthanide alkyls, ( eta 5(CH3)5C5)2MCH-[Si(CH3)3]2. The ( eta 5(CH3)5C5)2NdCH[Si(CH3)3]2 complexes react with H2 under mild conditions to yield the corresponding hydrides [( eta 5(CH3)5C5)2MH]2. These complexes have been found to be extremely active homogeneous olefin polymerization catalysts, as well as catalysts for olefin and acetylene hydrogenation. |
