π-Allylic Rhodium Complex Catalyzed Living Copolymerization of Arylallenes with Carbon Monoxide To Give Structurally Regulated Polyketones

摘要

All of the above results, including narrow molecular weight distribution of 2 during the polymerization reaction and forma- tion of the block copolymer 4, indicate that 1 catalyzes living copolymerization of the arylallenes with carbon monoxide to afford new polyketones under mild conditions.
