    Toward the Synthesis of Indenyl Molybdenum Compound [(η3-Ind)(η5-Cp)Mo(CO)2]: Modified Compounds and Structure of a Previously Unrecognized Intermediate
    摘要:
    The mechanism of synthesis of [(eta(3)-Ind')(eta(5)-Cp)Mo(CO)(2)] was studied on methyl-substituted derivatives (Ind' = 2-MeC9H6; 4,7-Me2C9H5). It was observed that the initial step involving reaction with HCl gives dimeric chloride species [{(eta(5)-Ind')Mo(CO)(2)(mu-Cl)}(2)]. This outcome differs from the structure suggested in the literature. Furthermore, it was demonstrated by various examples that compounds of the formula [{(eta(5)-Ind')Mo(CO)(2)(mu-Cl)}(2)] are convenient starting materials giving [(eta(3)-Ind')(eta(5)-Cp')Mo(CO)(2)] through the reaction with appropriate cyclopentadienides. The variability of this method was demonstrated on several examples including weakly donating Cp ligands bearing strong electron-withdrawing functional groups [C5H4COOMe, (1,2-MeOCO)(2)C5H3, and 1,2-((BuNHCO)-Bu-t)(2)C5H3] as well as Cp ligands bearing a pendant amine arm (C5H4CH2CH2NMe2). Similar eta(3)-indenyl complexes are formed when using other univalent six-electron ligands such as carbaborane (9-Me2S-7,8-nido-C2B9H10) or scorpionate (Tp, Tp*). The attempts to synthesize [(eta(3)-Ind)(eta(5)-Cp)Mo(CO)(2)] from [(eta(3)-C3H5)(eta(5)-Cp)Mo(CO)(2)] have failed because the initial reaction with HCl does not give the expected [{(eta(5)-Cp)Mo(CO)(2)(mu-Cl)}(2)] but trivial [(eta(5)-Cp)Mo(CO)(3)Cl].

    The course of the reactions between complex OsH2Cl2((PPr3)-Pr-i)(2) (1) and the functionalized cyclopentadienyllithium derivatives Li[C5H4(CH2)(2)E] (E = NMe2 (2), OMe (3)) strongly depenas on the solvent used. Thus, in the presence of donor solvents such as THF, the salts [OsH2eta(5)-C5H4(CH2)(2)E}((PPr3)-Pr-i)(2)][OsHCl2(CO)((PPr3)-Pr-i)(2)] (E = NMe2 [4][5], OMe [6][5]) with a carbonylated osmium anion are produced, while in hydrocarbon solvents the chloride salts [OsH2eta(5)-C5H4(CH2)(2)E}(PPr3)(2)]Cl (E NMe2 [4]Cl, OMe [6]Cl) are formed.
