title: Pd-catalyzed ring-opening copolymerization of 2-aryl-1-methylenecyclopropanes with CO to afford polyketones via alternating insertion of the two monomers and C [bond] bond C activation of the three-membered ring.
abstract: Pd-bpy complexes catalyze the ring-opening copolymerization of 2-aryl-1-methylenecyclopropanes with CO, affording the new polyketones composed of ring-opened structural units only. Kinetic and isotope-labeling studies revealed the mechanism of the reaction, which involves 1,2-insertion of the cyclic monomer followed by beta-alkyl elimination of the three-membered ring of the polymer chain.
