Vilsmeier-Haack reagent mediated synthetic transformations with an immobilized iridium complex photoredox catalystElectronic supplementary information (ESI) available. See DOI: 10.1039/c8nj05288c

An immobilized iridium complex photocatalyst Ir(ppy) 2 (PDVB-py) was synthesized by immobilization of the iridium complex onto the nanoporous vinylpyridine-divinylbenzene copolymer (PDVB-py). Its application for the synthesis of amides, nitriles, and anhydrides was reported via reactions under the action of the visible-light-driven in situ generated Vilsmeier-Haack reagent from CBr 4 in DMF. The results showed that this heterogeneous photocatalyst has extremely high activity and excellent stability to be recycled five times.
