Eight different flavin derivatives have been synthesized and the electronic effects of substituents in various positions on the flavin redox chemistry were investigated. The redox potentials of the flavins, determined by cyclic voltammetry, correlated with their efficiency as catalysts in the H2O2 oxidation of methyl p-tolyl sulfide. Introduction of electron-withdrawing groups increased the stability
合成了八种不同的黄素衍生物,并研究了不同位置的取代基对黄素氧化还原化学的电子影响。通过循环伏安法测定的黄素的氧化还原电位与其在甲基对甲苯基硫化物的H2O2氧化中作为催化剂的效率相关。吸电子基团的引入增加了还原的催化剂前体的稳定性。
