摘要
用循环伏安法与现场ESR方法结合,研究了6-硝基喹啉在DMSO介质中,Pt电极上的电化学行为,检测到了电化学还原的中间产物阴离子自由基,估算了阴离子自由基衰变的速度常数,提出了6-硝基喹啉电化学还原的机理。
The electrochemical reduction of 6-nitro-quinoline has been investigated on Pt electrode in DMSO media by cyclic voltammetry and controlled potential electrolysis, in combination with ESR in situ spectroscopy. The radical anion as the intermediate of 6-nitro-quinoline electrochemical reduction was detected. The rate constant of the decay of radical anion was evaluated as. The electrochemical reduction mechanisms of 6-nitronquinoline are suggested.
