Hydrogenolysis of the half-sandwich penta-arylcycopentadienyl-supported rare-earth metal dibenzyl complexes [(Cp)Ln(p-CH-CH-Me)(THF)] (Cp = CAr, Ar = 3,5-Pr-CH; Ln = Sc, La) afforded a bimetallic scandium complex [(Cp)Sc(H)(μ-OCH)] (2) with two terminal hydrido ligands, and a double-sandwich bimetallic lanthanum hydride complex [(Cp)La(μ-H)] (4) bearing the reduced Cp ligand. DFT calculations were conducted to elucidate the reaction profiles.
半夹心五芳基环戊二烯基支撑的稀土金属二苄基配合物[(Cp)Ln(p-CH-CH-Me)(THF)](Cp = CAr,Ar = 3,5-Pr-CH;Ln = Sc,La)的氢解反应得到了一种带有两个末端氢配体的双金属钪配合物[(Cp)Sc(H)(μ-OCH)](2),以及一种带有还原Cp配体的双夹心双金属镧氢配合物[(Cp)La(μ-H)](4)。进行了密度泛函理论计算以阐明反应过程。
