摘　　要：咪唑并杂环骨架不仅在许多天然产物中被认为是一个特殊的结构,在光电材料结构中也具有特殊作用。开发了一种通过简单的电化学脱氢C-H/N-H交叉偶联方法实现咪唑并杂环骨架与吩噁嗪的电化学偶联反应,具有较高的区域选择性和优异的产率。反应在一个简单的单室电解池中进行,并且不使用金属催化剂或过量的化学氧化剂。与之前的方法相比,无需使用昂贵的Pt电极和更高的反应电流,反应条件更温和。The imidazoheterocyclic is not only recognized as a special structure in many natural products,but also has a special role in the structure of optoelectronic materials.This work develops an electrochemical coupling reaction of imidazoheterocyclic with phenoxazine via a simple electrochemical dehydrogenation C-H/N-H cross-coupling method.This method is characterized by high regioselectivity and excellent yields.The reaction is conducted in a straightforward single-compartment electrolytic cell,eschewing the use of metal catalysts or excess chemical oxidizing agents.The necessity for expensive Pt electrodes and elevated reaction currents is negated,and the reaction conditions are more lenient than those observed in previous methods.
