摘要：

The ferrocene-chelating heteroscorpionate complex [(fc(PPh2){BH{(3,5-Me)(2)pz}(2)})PdMe] {(fc(P,B))PdMe, fc = 1,1-ferrocenediyl, pz = pyrazole} catalyzes the addition polymerization of norbornene and norbornene derivatives upon oxidation with [(Ac)Fc][BArF] {acetyl ferrocenium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate}. In situ reduction of [(fc(P,B))PdMe][BArF] in the presence of a substituted norbornene results in significant decrease of catalytic activity. Addition of one equivalent of oxidant restores the activity.
