A novel protocol for acid ionic liquid promoted C(sp(3))-H bond functionalization of alkyl azaarenes and nucleophilic addition to aldehydes was developed in good to excellent yields, which provides an efficient approach for the synthesis of alkyl-substituted azaarene derivatives. It is worthwhile to note that acid ionic liquid used for this reaction can be recycled and reused six times without a significant decrease in activity. (C) 2014 Elsevier Ltd. All rights reserved.

A highly efficient method is described for the sp(3) C-H bond functionalization of methyl aza-arenes in the presence of water under microwave irradiation and subsequent addition to aromatic aldehydes. This transformation represents an efficient way to synthesize 2-alkyl aza-arene derivatives from simple starting materials. (C) 2013 Elsevier Ltd. All rights reserved.
