Abstract
AbstractN‐heterocyclic compounds demonstrate wide applications ranging from natural compound production to coordination chemistry. Usually, the synthesis of N‐heterocyclic compounds is conducted under thermal conditions, mostly by Lewis acids or metal‐containing compounds as molecular catalysts. Here, we report a photocatalytic route for aryl azoline formation by mesoporous organosilica as visible light‐active and heterogeneous photocatalyst. Via formation of aromatic aldehydes with various amines, 2‐phenyl‐2‐imidazoline, 2‐phenyl‐2‐oxazoline, 2‐phenyl‐2‐thiazoline and their derivatives could be formed with high conversion and selectivity. Additionally, the organosilica photocatalyst showed high stability and reusability.
