Abstract

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)₂WCH-(CONHMe)CHMeNHMe (3) and Cp(CO)₂W(η³-CH-(COOC₂H₅)CHCH₂) (5), respectively. The C-C bond formation takes place at the a-carbon of the original allenyl fragment. The reaction of Cp(CO)₃WCH₂C=CH (2) with amine yields Cp(CO)₂W(η³-CH₂C(CONHR)CH₂) (4), in which the amido group is attached at the ß-carbon of the allyl group.
