Cross-Dehydrogenative Coupling of Strong C(sp³)–H with <i>N</i>-Heteroarenes through Visible-Light-Induced Energy Transfer

Abstract

The sustainable cross-dehydrogenative coupling of strong C(sp³)-H with <i>N</i>-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 <i>N</i>-heteroarenes and oxidants.
