Catalytic [2+2+2] Cycloaddition Polymerization of Diyne-Nitrile Monomers in the Presence of CoCl2-6H(2)O/Diphosphine/Zn
Cobalt-catalyzed [2+2+2] cocycloaddition reaction of 1,6-diynes and nitriles to generate substituted pyridines has been applied to the polymerization of diyne-nitrile monomers, the reaction of which proceeded smoothly in a step-growth fashion to provide linear polymers comprising pyridine structures in the main chain.
