The first example of palladium/norbornene cooperatively catalyzed polymerization is reported. It simplifies synthesis of functional aromatic polymers including conjugated polymers. Specifically, a multicomponent A2B2C-type polymerization is developed using Catellani-type ortho-amination/ipso-alkynylation reaction for preparing various amine-functionalized arylacetylene-containing polymers. Within a single catalytic cycle, the functional amine side-chains are site-selectively installed in situ during the polymerization process, which represents a major difference from conventional cross-coupling polymerizations and multicomponent polymerizations.
