Herein, we present the first catalytic direct olefination of methyl‐substituted heteroarenes with primary alcohols through an acceptorless dehydrogenative coupling. The reaction is catalyzed by a complex of the earth‐abundant transition metal manganese that is stabilized by a bench‐stable NNN pincer ligand derived from 2‐hydrazinylpyridine. The reaction is environmentally benign, producing only hydrogen
在本文中,我们介绍了通过无受体脱氢偶联与伯醇进行的甲基取代杂芳烃的首次催化直接烯烃化反应。该反应由富含地球的过渡金属锰的复合物催化,该复合物由衍生自2-肼基吡啶的稳定的NNN钳形配体稳定。该反应对环境无害,仅产生氢和水作为副产物。高效地选择性获得了大量的E-二取代烯烃。
