| Abstract: | 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 and water as byproducts. A large number of E‐disubstituted olefins were selectively obtained with high efficiency. |
