Abstract
Upon reaction with aqueous potassium hydroxide and aliphatic and aromatic a ldehydes 2 the salts 1, 2-diaminoquinolinium tosylate 4 and 1, 2-diaminoiso quinolinium tosylate 9 were converted into the corresponding 2-substituted [1,2,4]triazolo[1,5-a]quinolines 8 and [1,2,4] triazolo[5,1-a] isoquinoline s 13, respectively. The formation of the final products requires aerial oxi dation.
