Alkyne- and alkyl-tris(cyclopentadienyl) complexes of uranium(III)
Abstract
Treatment of cp3U(THF)(1)(cp =η-C5H5, THF = tetrahydrofuran) with diphenylacetylene affords the alkyne complex cp3U(Ph–CC–Ph); (1) reacts with RLi (R = Me, Bun) to give the alkyl compounds cp3URLi (3); hydrogenolysis of (3) in the presence of a terminal alkene R′(–H) leads to the formation of cp3UR′Li.
