for the oxidations of d -glucopyranose 6-phosphate and d -ribofuranose 5-phosphate by vanadium(V) in perchloricacid media have been measured spectrophotometrically in the visible region. The order with respect to [H + ] is less than unity for each reaction. The enthalpy and entropy of activations of the reactions are higher than those for the corresponding two-electron oxidations by chromium(VI). The

-glucopyranose 6-phosphate and d -ribofuranose 5-phosphate by chromium(VI) in perchloric acidmedia have been studied by u.v. spectroscopy. Each reaction is first order with respect to [chromium(VI)] and [substrate]. The reactions are acid-catalysed and accelerated by the addition of sodium perchlorate. The mechanism of the reactions is discussed.
