concomitant electrochemicalreduction of 9,10-phenanthrenequinone and benzenediazoniumtetrafluoroborate, under constant potential conditions (−0.5 V vs Ag/Ag+), has been performed in different organic solvents. An interesting entry to new C–C radical coupling products is here described. Another cathodic pathway where the anion radical intermediate acts as an EGB is also described. The electrochemical behaviour
在不同的有机溶剂中,在恒定电势条件下(-0.5 V对Ag / Ag +),进行了9,10-菲醌和四氟硼酸苯重氮的伴随电化学还原。这里介绍了一个新的C–C自由基偶联产品的有趣条目。还描述了其中阴离子自由基中间体充当EGB的另一种阴极途径。给出了系统的电化学行为和机理建议。
