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.
