Toward the Synthesis of Indenyl Molybdenum Compound [(eta(3)-Ind)(eta(5)-Cp)Mo(CO)(2)]: Modified Compounds and Structure of a Previously Unrecognized Intermediate

Popis výsledku v původním jazyce

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 carba
