In a new and simple process for preparing 5-hydroxymethyl-2-furaldehyde from mono-, oligo- and poly-saccharides, which uses immonium or ammonium salts, direct heating of the reagent and the starting material, both in solid phase, gave directly 5-hydroxymethyl-2-furaldehyde with a good purity, avoiding production of secondary products.The use of a polymeric form of the reagent constitutes an extension of the method toward an eventual industrial application.Under special conditions, a one-pot dehydration-halogenation sequence gave 5-bromomethyl-(or 5-chloromethyl)-2-furaldehyde.
