Abstract

The heterocyclic ionic liquid-catalyzed direct oxidative amination of benzylic sp³ C–H bonds via intermolecular sp³ C–N bond formation for the synthesis of N-alkylated azoles under metal-free conditions is reported for the first time. The catalyst 1-butylpyridinium iodide can be recycled and reused with similar efficacies for at least eight cycles.
