Abstract
The sustainable cross-dehydrogenative coupling of strong C(sp3)–H with N-heteroarenes has been developed using an efficient organic photocatalyst. It features atomic- and step-economy, and acid-free conditions. Mechanism studies suggest a previous elusive energy transfer pathway from photocatalyst to N-heteroarenes and oxidants.
