Abstract
AbstractTreatment of poly(chlorotrifluoroethylene) with allyltin reagents results in the clean replacement of chlorine by the allyl group under free‐radical–chain conditions (AIBN, allyltributyltin), affording about a 10% degree of functionalization. An improved method using one‐electron reduction of the polymer with cobalt(II) (generated by reduction of chloro(pyridine)bis(dimethylglyoximato)cobalt(III) with Mg) and allyltributyltin gives 50% functionalization. Further modification of the allyl group is realized through hydroboration‐oxidation to the alcohol and subsequent Cr(VI) oxidation to the acid.
