Herein, the first example of base‐metal‐catalyzed dehydrogenative coupling of diols and amines to selectively form functionalized 1,2,5‐substituted pyrroles liberating water and hydrogen gas as the sole by‐products is presented. The reaction is catalyzed by pincer complexes of earth‐abundant cobalt.
在此,提出了第一个例子,即碱金属催化的二醇和胺的脱氢偶联,选择性地形成官能化的1,2,5-取代的吡咯,释放出水和氢气作为唯一的副产物。富含稀土的钴的钳状配合物可催化该反应。
