OXIDES OF 3-METHYL-1,2,4-BENZOTRIAZINE
Atallah, Raja H.,Nazer, Musa Z.
, p. 1793 - 1796 (2007/10/02)
The previously prepared 3-methyl-1,2,4-benzotriazine oxide is shown to be the 4-oxide 5.Synthesis and structores of other isomeric and related oxides are described.A modification of a previously described synthesis of 1,2,4-benzotriazines produces purer products in higher yields.
