Cross-Dehydrogenative Coupling of Strong C(sp3)–H with N-Heteroarenes through Visible-Light-Induced Energy Transfer
摘要:
The sustainable cross-dehydrogenative coupling of strong C(sp(3))-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.

inside job: The conformational interconversion of cyclohexane occurs at a higher rate in the interior of gated molecular baskets (see picture) than in bulk free solvent or a vacuum. The acceleration results from more favorable noncovalent bonding, and hence stabilization of the transitionstate, of the encapsulated compound.

We report herein a protocol for the selective activation of C(sp3)–H bonds based on the interplay of two readily available organic catalysts and their successful implementation in cross-coupling azaarenes with alkanes. This Minisci-like reaction is promoted by visible light at room temperature and is free from chemical oxidants, metals, and chlorinated solvents. A wide range of substrates are compatible
