N2  - The cyclopentadienyl - and indenyl-lanthanoids, (C5H5)2Yb( dme ) ( dme = 1,2- dimethoxyethane ), (C9H7)2Yb( thf )2 ( thf = tetrahydrofuran ), (C5H5)2Eu( thf )n (n = 0.5 or 1), (C9H7)2Eu( thf ), (C5H5)3Sm, (MeC5H4)3Sm, and (C9H7)3Sm( thf ) have been prepared by ligand exchange reactions of (C6F5)2Yb, (C6F5)2Eu, and a pentafluorophenylsamarium species with cyclopentadiene , methylcyclopentadiene , or indene. This synthetic method has particular significance for the indenyllanthanoids . An explosive product was obtained from (C6F5)2Yb and methylcyclopentadiene. Reactions of ( PhCC )2Yb with cyclopentadienes and indene have yielded (C5H5)2Yb( dme ), (MeC5H4)2Yb( dme ), and (C9H7)2Yb( thf )2, but (C5H5)2Yb did not undergo ligand exchange with phenylacetylene.
