文摘In two previous papers, we reported the syntheses of cyclopentadienyl dichlorides of lower lanthanides and their catalytic activities of polymerization for dienes. A new series of organolanthanides containing the indenyl group and having the formulae C9H7LnCl2·(C4H8O)x(Ln=Nd,Pr,Gd, and Sm; C9H7=indenyl; C4H8O=tetrahydrofuran; x=0,1,2,3) and C9H7LnCl2·HCl·(C4H8O)x (Ln=Nd, Pr, and Sm;x=0,1,2) have also been synthesized.
