摘要：

[(η3-C3H5)3WCl]2 reacts with alkylmagnesium halides to give (η3-C3H5)3WR species in which the β-H-atoms of the alkyl group interact with the metal atom in an agostic manner. (η3-C3H5)3WEt reacts with trimethylphosphine with intramolecular protonation of an allyl group to give (η3-C3H5)2(η2 -CH2: CH2)W(PMe3)2 with elimination of propene, and with butylisocyanide with insertion into the WEt bond to give (η3-C3H5)3(η 2-EtC: NC4H9)W. Methyl-substituted allylmagnesium halides react with [(η3-C3H5)3WCl]2 to give (η3-C3H5)3(η 3-MeC3H4)W and (η3-C3H5)3(η3 -1,3-Me2C3H3)W as a mixture of isomers. © 1990.
