, p. 2195 - 2199 (2018)
A strategy for oxidative Csp3-H/N-H cross-coupling is presented. This reaction successfully utilizes 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and tert-butyl nitrite (TBN) as co-catalysts to construct the biomedical applicable biheteroarene

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.
