Abstract
Inverse vulcanized polymers(IVPs)that generated from elemental sulfur and smaller amounts of alkenes have found broad promising applications such as cathode materials for Li-S batteries,dynamic and re-pairable materials,optics applications,and metal sorption.However,their exploration in organic synthe-sis is still unprecedented.Here we first report the application of inverse vulcanized polymers in catal-ysis for organic transformations.A biomass-derived inverse vulcanized polymer(IVP-EAE)is found to be capable of catalyzing cross-coupling reactions in a transition-metal-free fashion under visible light.This method allows the direct C-H functionalization of pyrroles and N-arylacrylamides with(hetero)aryl halides,respectively,leading to the formation of two sets of structurally important scaffolds including pyrrole-containing biaryls and 3,3'-disubstituted oxindoles with high selectivity.We anticipate this study will not only unveil the new potential of IVPs,but also offer a distinct type of catalysts for organic trans-formations.
