New 2D membrane reactor improves photocatalytic synthesis

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 and carbonyl compounds that often require dehydrating agents, strong acids, or costly catalysts, posing significant challenges for sustainable manufacturing.
