- STUDIES ON AS-TRIAZINE DERIVATIVES. IX. SYNTHESIS OF 5-SUBSTITUTED 1,2,4-TRIAZINE DERIVATIVES THROUGH AN ADDITION REACTION AND SUBSEQUENT OXIDATION
-
The addition reactions of various nucleophiles to 6-methyl-3-phenyl-1,2,4-triazine (1) were investigated and a practical preparation of 1 was developed.The reactions showed many similarities to those of quinazoline (at the 4-position) and acridine (at the

- STUDIES ON as-TRIAZINE DERIVATIVES. VII. RESEMBLANCE BETWEEN as-TRIAZINES AND QUINAZOLINES IN NUCLEOPHILIC ADDITION-ELIMINATION REACTIONS.
-
Alike 4-chloroquinazoline, 5-chloro-1,2,4-triazines (as-triazines) reacted with aromatic aldehydes in the presence of 1,3-dimethylbenzimidazolium iodide under basic conditions to give 5-aroyl-as-triazines.The Grignard reaction of 5-cyano-as-triazine with arylmagnesium bromides failed to give any significant product.Some analogy of as-triazines with quinazolines, in their chemical properties, was additionally investigated.
