Liquid phase oxidative cyclization of crotonaldehyde (2-butenal) to furan was for the first time found to proceed effectively in a CuCl2, CuCl or PdCl2 or PdCl2 aqueous solution containing alkali or ammonium halides and HCl as additives in the temperature range of 350–378 K. Chlorides of iron, manganese and gold were inactive. CuCl has almost the same activity as CuCl2, showing that the reaction can proceed catalytically.
