  Permethyl Yttrocene 2-Furyl Complexes:  Synthesis and Ring-Opening Reactions of the Furyl Moiety

  摘要：

  Permethyl yttrocene 2-furyl ate-complexes Cp*Y-2(mu-C4H3O)(mu-Cl)Li(THF)(2) (1, Cp* C-5-Me-5) and Cp*Y-2(mu-C4H3O)(2)Li(TMEDA) (2) were obtained by reaction Of Cp*(2)(mu-Cl)(2)Li(OEt2)(2) with 1 and 2 equiv of 2-lithiofuran, respectively. Furan is metalated by (Cp*2YH)2 in hydrocarbon solvents to give the 2-furyl complex Cp*Y-2(eta(2)-C4H3O) (3). With Lewis bases, 3 reacts to give the adducts Cp*Y-2(eta(1)-C4H3O)(L) (L = THF, 4; pyridine), of which 4 was crystallographically characterized. Compound 3 decomposes through deprotonation and ring-opening of the 2-furyl group to give the (crystallographically characterized) bimetallic ynylenolate complex (Cp*Y-2)(2)(mu-OCH=CHCdropC) (5). With excess H-2, 3 is transformed into the crystallographically characterized oxo-complex (Cp*Y-2)(2)(mu-O) (6), free furan, and n-butane. In the presence of a large excess of furan, this reaction stops at the enolate species Cp*(2)-YOCH=CHEt.
