  摘要：

  The reaction of Li-2[eta(5):eta(5);(C5H3CO2Me)(2))Mo-2(CO)(6)] (from trans-(eta(5):eta(5)-(C5H3CO2Me)(2))Mo-2-(CO)(6)) (1) with MeI yields (eta(5):eta(5)-(C5H3CO2Me)(2))Mo-2(CO)(6)Me-2 (3). The reaction of cis-(eta(5):eta(5)-(C5H3CO2Me)(2))Mo-2(CO)(6) (2) with I-2 leads to the formation of (eta(5):eta(5)-(C5H3CO2Me)(2))Mo-2(CO)(6)I-2 (4). The X-ray structure of 4 has been determined; The reactions of 1 with P-donor nucleophiles (PPhMe2, PPh2Me, P(n-Bu)(3), and PMe3) and (eta(5):eta(5)-(C10H8)M-2(CO)(6) (M = Mo and W) with PMe3, in the presence of 1 equiv of Me3NO, produce CO labilization and formation of the dinuclear zwitterions (eta(5):eta(5)-(C5H3CO2Me)(2))Mo-2(CO)(5)L-2 and (eta(5):eta(5)-(C10H8)M-2(CO)(5)(PMe3)(2) (M = Mo and W) 5, 6, 7, 8, 9, and 10, respectively). The dimer [(eta(5)-C5H4CO2Me)Mo(CO)(3)](2) (11) was obtained by reaction of Mo(CO)(6) with sodium carbomethoxy cyclopentadienide in THF followed by oxidation with ferric sulfate. The reaction of 11 with PPh2Me in the presence of 1 equiv of Me3NO gives the disproportionation species [(eta(5)-C5H4CO2Me)Mo(CO)(2)(PPh2Me)(2)(+)][eta(5)-C5H4CO2Me)Mo(CO)(3)(-)] (12). The electrochemical study of 3 and 4 is reported. Two distinct cathodic waves are observed in the voltammetric reduction of 4, the less negative one with a coupled anodic peak at high sweep rate in PC.
