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
Elimination of benzotriazolyl group in N-(α -benzotriazol-1-ylalkyl)amides and N-(α -benzotriazol-1-ylalkyl)sulfonamides: Their self-coupling and cross-coupling reactions with carbonyl compounds

The elimination of benzotriazolyl group from N-(α -benzotriazol-1-ylalkyl)amides and N-(α -benzotriazol-1-ylalkyl)sulfonamides are readily realized with samarium diiodide as a reducing agent. The resulting intermediates undergo a dimerization or cross-coupling reaction with carbonyl compounds, thus affording the corresponding dimers or α-hydroxyalkylated sulfonamides in moderate yields.
