Tricyclopentadienylneodymium and -lutetium react with sec-butyl lithium and terf-butyl lithium to form sec-butyl- and tert-butyl(dicyclopentadienyl)neodymium and -lutetium, which decompose to the corresponding dicyclopentadienyllanthanide hydride complexes. Dicyclopentadienyl-bis-(trimethylsilyl)methylsamarium and -lutetium are made from dicyclopentadienylsamarium or -lutetium chloride and bis(trimethylsilyl)methyl lithium. They react with hydrogen to form the corresponding dicyclopentadienyllanthanide hydride complexes.

Abstract In the polymerization of chloroprene in the presence of butyl lithium, a substantial role is ascribed to reactions of deactivation of growing chains, which prevents the possibility of attaining a high degree of conversion. Kinetic data indicate the anionic mechanism of the process.
