Sažetak
L-Ascorbate reduces substituted nitrosobenzenes in aqueous solution, in a process that includes a cyclic transition state composed of ascorbate and nitrosobenzene and in which concerted electron and proton transfer leads to the products. The results suggest that the mechanism by which ascorbate interacts with the -tocopheroxyl radical in the exceptionally important tocopherol– ascorbate redox cycle also includes the corresponding cyclic transition state.
