Redox dependence of the reaction of alpha-alkoxyalkyl radicals with a series of oxidants.

Abstract:

Oxygen and oxidants enhance the sensitivity of cells to radiation. To understand this effect at the mechanistic level, the redox dependences for the reactivity of weakly reducing alpha-monoalkoxyalkyl radicals of 1,4-dioxane and tetrahydrofuran with a series of oxidants, for example, quinones, viologens, and nitro-arenes, with one-electron reduction potentials E71 values ranging from -80 to -640 mV, have been determined using the technique of pulse radiolysis. The second-order rate constants ...
