Abstract
In aqueous solution benzotriazole 1-oxide and its 4- and 6-nitro-derivatives exist largely in the N-oxide tautomeric forms. In ethanol the unsubstituted and 6-nitro-compounds are predominantly in the N-hydroxy-forms, but the 4-nitro-compound exists as a mixture of comparable amounts of the two tautomers.Keywords
