Chinese researchers have developed a photocatalytic membrane reactor that dramatically improves the synthesis of imines—a class of compounds essential to the production of pharmaceuticals, agrochemicals, and advanced synthetic materials. Characterized by their C=N bond, imines are critical precursors in the synthesis of various high-value compounds, including oxaziridines, cucurbiturils, and quinolines. However, traditional imine synthesis methods rely on condensation reactions between amines an...
