OXIDATIVE DEGRADATION OF MONOSACCHARIDES BY IRON(III) CHLORIDES WITH A NEAR-UV TO VISIBLE LIGHT UNDER AEROBIC ATMOSPHERE.

Article abstract of DOI:10.1246/bcsj.57.997

Monosaccharides were oxidatively degraded by FeCl//3 with irradiation of a near-UV to visible light under aerobic atmosphere. D-Fructose and D-arabinose were degraded to D-erythrose in a yield of more than 80 mol%. D-Glucose and D-mannose were at first degraded to D-arabinose, which was subsequently degraded to D-erythrose, while d-ribose was directly degraded to d-erythrose and D-glyceraldehyde. The degradation processes were selective, and these reactions were shown to proceed via formation of an Fe(III)-monosaccharide complex. The kinetic data and other features of these reactions are also discussed.
