Acceptorless Dehydrogenation of Nitrogen Heterocycles with a Versatile Iridium Catalyst

Abstract

Gas up: A cyclometalated iridium complex is found to catalyze the dehydrogenation of various benzofused N-heterocycles, thus releasing H2. Driven by as low as 0.1 mol % catalyst, the reaction affords quinolines, indoles, quinoxalines, isoquinolines, and β-carbolines in high yields.
