Abstract: The formation of superoxide ion (02-.) via one-electron transfer from substituted N, N-dimethylanilines to singlet oxygen (IO2) was examined in phosphate buffer by employing a water-soluble oxygen source and a combination of p-nitrotetrazolium blue (NBT) and superoxide dismutase (SOD) as a detecting reagent for 02--. When a solution of an electrondonor-substituted N, N-dimethylaniline, NBT, and 3-(1, 4-epidioxy-4-methyl-1, 4- ...
