The reduction of I2 by 1-hydroxyalkyl radicals in aqueous solution. A pulse radiolysis study

The one electron reduction of iodine by various 1-hydroyalkyl radicals in aqueous solution is described, which leads first to the formation of I2−, and to I− at longer times. Rate constants of 5×109, 6.5×109, or 8×109 dm3 mol−1 s−1 were obtained for the reaction between iodine and the radical of methanol, ethanol or 2-propanol, respectively.
