Synthesis of 5-bromo-2-furfural under solvent-free conditions using 1-butyl-3-methylimidazolium tribromide as brominating agent
The development of a facile and general method for the preparation of 5-bromo-2-furfural is described. An excellent yield of high regioselectivity came out of the bromination reaction of 2-furfural with 1-butyl-3- methylimidazolium tribromide under solvent-free conditions.
