Nickel-catalyzed decarbonylative polymerization of 5-alkynylphthalimides: A new methodology for the preparation of polyheterocycles
A nickel-catalyzed decarbonylative cycloaddition was developed, in which 5-alkynylphthalimides reacted to afford a new type of polyisoquinolone. It was demonstrated for the first time that decarbonylative cycloaddition can be an elementary process of polycondensation for the preparation of heterocyclic polymers.
