摘要：

Reaction of [MoBr(eta2-MeC2R)2(eta-C5H5)] (R = Me, or Ph) with Li[N(SiMe3)2] leads to a dehydrohalogenation reaction and the unexpected formation of the three-electron sigma,eta2-prop-2-ynyl complexes [Mo(sigma,eta2-CH2C2R)(eta2-MeC2R)(eta-C5H5)]; treatment of these reactive molecules with the proton source CF3CO2H affords the bis-alkyne complexes [Mo(O2CCF3)(eta2-MeC2R)2(eta-C5H5)], whereas reaction with carbon monoxide leads to a novel carbon-carbon bond forming reaction, and formation of the X-ray crystallographically identified complex [Mo{eta2,eta3-C(Me)C(O)C(Me)C(Me)C-CH2}(CO)(eta-C5H5)].
