摘要：

The reactions of Cp(CO)3WCH = C = CH2 (1) with excess methylamine and with 1 equiv of ethanol produce the aza metallacycle complex Cp(CO)2-activated-WCH-(CONHMe)CHMENHME (3) and Cp(CO)2W(eta-3-CH-(COOC2H5)CHCH2) (5), respectively. The C-C bond formation takes place at the alpha-carbon of the original allenyl fragment. The reaction of Cp(CO)3WCH2C = CH (2) with amine yields Cp(CO)2W(eta-3-CH2C(CONHR)CH2) (4), in which the amido group is attached at the beta-carbon of the allyl group.
