An efficient one-pot N-alkylation of benzimidazole and benzotriazole from carbonyl compounds and tosylhydrazide has been accomplished via copper powder-catalyzed N - H bond insertion affording N-alkylated products in good yields. The reaction can tolerate a wide range of carbonyl compounds, such as aryl, alkyl, heterocyclic and α,β-unsaturated ketones, and aldehydes.

3-Aryl-1,2,4-benzotriazines were conveniently prepared in moderate to good yields from 1,l-bis(benzotriazol-1-yl)methylarenes with allylsamarium bromide/hexamethylphosphramide (allylSmBr/HMPA). Preliminary results indicate that HMPA may enhance the reduci

The Mitsunobu reaction was used in the preparation of chiral triazole derivatives. The reactions gave good to excellent yields with large substrate scope. Complete stereochemistry inversion was obtained, making this strategy one practical approach for the
