- Hydrazidines, IV. - Reaction of Hydrazidines with 1,2-Bifunctional Compounds
-
Hydrazide hydrazones 1 react with 1,2-bifunctional compounds (2, 21, 23, 26, 30, 32) to give preferentially 4-amino-1,2,4-triazines (9, 13, 22, 25, 27, 31, 35).Some reactions of these substances are described.

- STUDIES ON as-TRIAZINE DERIVATIVES. VI. INTRODUCTION OF ARYL GROUPS TO THE 5-POSITION OF 1,2,4-TRIAZINES
-
1,2,4-Triazines derivatives possessing different aryl groups at the 5- and 6-positions were synthesized by the addition of arylmagnesium bromides (Ar'MgBr) to 6-aryl(Ar)-3-methyl-1,2,4-triazines with the free 5-position, and subsequent oxidation of the resulting 2,5-dihydro intermediates.The synthesis of 6-aryl-3-methyl-1,2,4-triazines is also described.
