摘要：

Polyethers containing viologen moieties were prepared by the reaction of tosylated polyethers with bipyridine. Viologen moieties of these polymers having  ((CH2)2O)n  chains were reduced into the cation radicals by sodium dithionite in dichloromethane, methanol, and benzene. The reduction of vicinal dibromide, ethyl 2,3‐dibromo‐3‐phenylpropionate using these polymers as electron‐transfer catalyst (ETC) was performed in dichloromethane to obtain ethyl cinnamate in good yield.
