An efficient and environmentally benign synthesis of phenanthridine by electrochemically oxidative cyclocoupling of biaryl vinyl azide with sodium azide and benzenesulfonyl hydrazide, respectively, is reported. The reaction is carried out in undivided cell at room temperature, without additional metal‐catalysis or exogenous oxidant.
据报道,分别通过联芳基乙烯基叠氮化物与叠氮化钠和苯磺酰肼的电化学氧化环偶联,可有效地和环保地合成菲啶。该反应在室温下在无分隔的池中进行,无需额外的金属催化或外源氧化剂。
