5′-Mercapto-1′H-1,2,4-triazol-3′-yl-isoquinolinium salts (6) were synthesised by the reaction of ortho-acyl phenylacetones (2) or the corresponding pyrylium salts (3) and 5-amino-2,3-dihydro-1H-1,2,4-triazole-3-thione (5). Treatment of thioles 6 withα,ω-dibromoalkanes led to type 15, 16 and 17 isoquinolinium salts condensed with thiazole, thiazine and thiazepine rings. When 6 are reacted with dibromomethane
