A novel conversion of acetylenic 1,2,4-triazoles into 3-alkyl-5-arylpyridazines
Crowley, Patrick J.,Russell, Sally E.,Reynolds, Laurence G.
, p. 8966 - 8973 (2007/10/03)
Bromination of 2-aryl-1-[1,2,4]triazol-1-ylalk-3-yn-2-ols gives 6-bromo-7-hydroxy-5-alkyl-7-aryl-7,8-dihydro-[1,2,4]triazolo[1,2-a]pyridazin-4-ylium salts, which are converted by treatment with strong alkali into novel 3-alkyl-5-arylpyridazines.
