Concerted two-proton–coupled electron transfer from catechols to superoxide via hydrogen bonds

The reaction mechanism between electrogenerated superoxide (O2−) and catechols as an important functional group of polyphenolic antioxidants was investigated based on electrochemical and electron spin resonance (ESR) spectral measurements and supported by density functional theory (DFT) calculations...
