Abstract
Highly functionalized alternating polyketones which possess epoxide groups in the side chains are synthesized by cationic palladium(II) complex catalyzed copolymerization of vinyl epoxides (non-conjugated diene monoepoxides) with carbon monoxide. Catalytic amounts of formic acid and 1,4-naphthoquinone promote the copolymerization significantly without effecting the epoxide group, with [Pd(L)(MeCN)2](BF4)2 (L = (R,R)-Me-DUPHOS) as the catalyst.
