摘要
Recently, it was found in this laboratory that nitroxide is an oxidant for some biologically active substances, e. g., ascorbic acid and cysteine, and some mechanistic studies involving electron transfer have been reported. In this letter we wish to report a detailed study on the redox reaction between 2,2,6, 6-tetramethyl-4-hydroxypiperidine nitroxide (Ⅰ)
