We herein present a metal-free, electrosynthetic method that enables the direct dehydrogenative coupling reactions of phenols carrying electron-withdrawing groups for the first time. The reactions are easy to conduct and scalable, as they are carried out in undivided cells and obviate the necessity for additional supporting electrolyte. As such, this conversion is efficient, practical, and thereby
我们在此提出了一种无金属的电合成方法,该方法首次实现了带有吸电子基团的酚的直接脱氢偶联反应。该反应易于进行且可扩展,因为它们在未分开的电池中进行,并且消除了额外支持电解质的必要性。这样,由于废物的产生被最小化,这种转化是有效的,实用的,并且因此是环境友好的。该方法具有广泛的底物范围,并且可以耐受多种官能团,为新型多齿配体甚至杂环(如二苯并呋喃)提供了易于获得的前体。
