Synthesis and polymerization of alkylplatinum complexes containing two vinyl groups

Oxidative addition of alkyl or acyl halides containing a vinyl substituent (RX: CH2=CHO2CCH2Br, CH2=CMeCO(2)CH(2)CH(2)Br, CH2=CHCOCl, CH2=CHC6H4CH2Cl) to [PtMe(2)(v-bipy)], v-bipy=4-methyl-4'-vinyl-2,2'-bipyridine, gives the corresponding alkylplatinum(IV) complexes [PtXMe(2)R(v-bipy)], which contain two vinyl groups and thus are suitable precursors to cross-linked vinyl polymers with organoplatinum(IV) substituents. Each platinum(IV) monomer can exist in three isomeric forms, one formed by trans and two formed by cis oxidative addition. Copyright (C) 1996 Elsevier Science Ltd.
