A Metal-free Route to Substituted Imidazolidines via Ring-Opening Cyclization (ROC) of Activated Aziridines with N-Benzylanilines: DA-COP Catalyzed Photo-Oxidative C-H activation

A metal-free, conjugated organic polymer (TPA-PQ) catalyzed intramolecular C-H functionalization strategy for the synthesis of imidazolidines in the presence of light and O2 is reported. This heterogeneous catalytic protocol is...
