Lewis acid catalyzed alteration of annulation pattern allowed formation of arylquinolines via C–H functionalization of nitrosoarenes and C–C cleavage of (epoxy)styrene.
Thermosetting polyquinoline polymers, methods for preparing the polymers, and methods for curing the polymers are provided. The polymers incorporate quinoline repeat units and end groups which include a reactive acetylene functionality. On heat treatment, the reactive end groups form cross-links which render the polymer insoluble and extend the polymer's operating temperature.
