摘要：
The complex RuCl2(PMe3)(C6Me6) (1) reacts with homopropargylic alcohol derivatives HC=CCH2Ch2OY CH2OY (2a-d) (Y=COC(Me)-CH2, COCH=CH2, CH2C(Me)=CH2, CO(CH2)8CH=CH2) and NaPF6 in methanol to give a variety of cationic ruthenium carbene complexes containing a polymerizable chain end [Ru-{=C(OMe)(CH2)3OY}Cl(PMe3)(C6Me6)]+PF6- (5a-d). These salts are easily deprotonated by tBuOK to produce the corresponding neutral ruthenium alkenyl monomers Ru{C(OMe)=CHCH2CH2OY}Cl(PMe3)(C6Me6) (6a,b). Radical copolymerization of methyl methacrylate with the monomer HC-CCH2CH2OCOC(Me)--CH2 (2a) or the monomer Ru{C(OMe)=CHCH2CH2OCOC(Me)=CH2}-Cl(PMe3)(C6Me6)(6a) leads to the formation of free alkyne containing copolymer 4 or of a ruthenium containing polymer 7.
