Synthesis, Structure, and Ring-opening Metathesis Polymerization of η 5 -Pentamethylcyclopentadienyl-(η 5 -exo-tricyclo (5.2.1.0 2,6 )deca-2,5,8-trien-6-yl) Iron
摘要
η 5 -Pentamethylcyclopentadienyl-(η 5 -exo-tricyclo(5.2.1.0 2,6 )deca-2,5,8-trien-6-yl) iron(3) was synthesized and characterized by 1 H NMR, 13 C NMR, MS, elemental analysis, IR, UV and X-ray diffraction analysis. Compound 3 was polymerized with ring-opening metathesis polymerization(ROMP) initiator (PCy3)2Cl2Ru=CHPh. 1 H NMR and IR spectra revealed the presence of CH=CH units in the polymer and supported the ROMP mechanism. GPC analysis of the polymer showed that the weight-average molecular weights(Mw) was 5967, and the polydispersity in- dex(PDI) was 1.16. The polymer was also investigated by UV and cyclic voltammetry. Keywords Ferrocene; Metathesis; Ring-opening polymerization; Cyclic voltammetry; X-ray diffraction Article ID 1005-9040(2009)-05-662-04
