5-Halo-2-furaldehydes Ia, Ib react with trimethylamine in aprotic solvents to furnish 5-trimethylamonium salts of 2-furaldehyde IIa, IIb.The reactivity of this salt was utilized for a simple preparation of 5-substituted 2-furaldehydes IV in water at room temperature.The possibility to synthesize azomethines V and ethylenes VI, having the trimethylammonium group in position 5 of the furan ring maintained, is discussed.
