Organoplatinum(IV) derivatized vinyl monomers and polymers prepared by oxidative addition

Organoplatinum(IV) complexes of general formula [PtXMe(2)R(NN)], containing vinyl substituents, have been prepared by oxidative addition of RX, (RX = methyl 2-(bromomethyl)acrylate, 2-(bromomethyl)acrylic acid, 2-bromoethyl methacrylate, acryloyl chloride, and chloromethyl styrene), to [PtMe(2)(NN)], NN = 2,2'-bipyridine or 4,4'-di-tert-butyl-2,2'-bipyridine. Polymers with organoplatinum(IV) substituents have been prepared either by free radical polymerization of the organoplatinum(IV) derivatized monomers or by free radical polymerization of the organic monomers, followed by the oxidative addition of the C-X substituents of these polymers to [PtMe(2)(NN)]. In the latter method, it is generally not possible to metallate all the C-X bonds, but a high degree of platinum incorporation can be achieved.
