further gives 3a by removing hydrogen ion. Notably, the residual
iodine anion regenerate the catalyst TBAI and hydrogen cation

In summary, a diverse array of 1,2,3-benzotriazine-4-(3H)-
ones were prepared from 2-aminobenzamides and tert-butyl
nitrite in good to excellent yields. Compared to previous reports,
this novel protocol is distinguished by (1) acid-free and mild
conditions, (2) operational simplicity, (3) high yields, (4) broad
substrate scope and (5) water and tert-butyl alcohol as green
byproducts. Further developments of tert-butyl nitrite based
novel synthesis of N-heterocycles are currently in progress in our
laboratory.
