Under UV irradiation in the presence of iron(III) chloride or iron(III) triflate in pyridine, D-glucose, D-mannose, and D-galactose underwent a selective bond cleavage at the C1–C2 position, producing 4-O-formyl-D-arabinopyranose and 4-O-formyl-D-lyxopyranose. D-Fructose, under the same conditions, gave arabino-γ-lactone. The reaction was interpreted in terms of the photoinduced electron transfer within

Photoreaction of D-glucose, D-mannose, and D-galactose in pyridine in the presence of iron(III) chloride induced a selectivebondcleavage at C1–C2 position, and produced corresponding 4-0-formyl-D-aldopentopyranoses.
