Potassium <i>tert</i>‐Butoxide‐Promoted Acceptorless Dehydrogenation of N‐Heterocycles

Abstract

Abstract Potassium tert ‐butoxide‐promoted acceptorless dehydrogenation of N‐heterocycles was efficiently realized for the generation of N‐heteroarenes and hydrogen gas under transition‐metal‐free conditions. In the presence of KO t Bu base, a variety of six‐ and five‐membered N‐heterocyclic compounds efficiently underwent acceptorless dehydrogenation to afford the corresponding N‐heteroarenes and H 2 gas in o ‐xylene at 140 °C. The present protocol provides a convenient route to aromatic nitrogen‐containing compounds and H 2 gas. magnified image
