    摘要:
    The reactions of the substituted tetramethylcyclopentadienes [C5Me4HR] [R = ethyl (1), n-propyl (2), i-propyl (3), cyclopentyl (4), cyclohexyl (5), 4-NMe2Ph (6)] with Mo(CO)(6) in refluxing xylene gave the corresponding dinuclear metal carbonyl complexes [eta(5)-C5Me4R](2)Mo-2(CO)(6) (7-11), while similar treatment of [C5Me4H(4-NMe2Ph)] (6) with Mo(CO)(6) afforded an unexpected product [(eta(5)-C5Me4(4-NMe2Ph))MoO2] 2(mu-O) (12). All the new complexes were fully characterized. The molecular structures of 7, 8, 11 and 12 have been determined by X-ray single crystal diffraction. (C) 2013 Elsevier B.V. All rights reserved.

    diffraction. Reaction of 1b with Co atoms afforded a single product, the dinuclear cluster [(η5-tBu3Cp)Co}2H3] (4b), whose molecular structure was determined by single-crystal X-ray diffraction. Both, 4a and 4b exhibit extremely short Co-Co distances [2.244(1) (4a) and 2.242(1) Å (4b)], as found for the Me5Cp analog [(η5-Me5Cp)Co}2H3] (4c).

    mixture with LiAlH4 or LiR (R = CH3, C6H5, P(C6H5)2) gave the corresponding substituted tetramethylcyclopentadienide anions [C5(CH3)4]CH(CH3)R}− (R = H, CH3, C6H5, P(C6H5)2) in high yields. Reaction of these substituted tetramethylcyclopentadienide anions with FeCl2 in THF led to the formation of the corresponding substituted ferrocene complexes, [C5(CH3)4]CH(CH3)R}2Fe, in moderate yields.
