Electrochemically initiated [3 2] cycloaddition reactions of readily available and less toxic starting materials enable a facile synthesis of pyrazolines and pyrazoles. Application of a biphasic system and sodium iodide in a dual role as mediator and electrolyte allows for selective reactions with outstanding robustness towards scalability.
电化学引发的 [3 2] 环加成反应容易获得且毒性较低的起始材料使吡唑啉和吡唑的合成变得容易。双相系统和碘化钠作为介质和电解质的双重作用的应用允许选择性反应对可扩展性具有出色的鲁棒性。
