Abstract
The cyclization of 1-amino-2-mercapto-5-[5-methyl-1-(4-methylphenyl)-1,2,3- triazol-4-yl]-1,3,4-triazole with various alpha-haloketone in absolute etha nol yields 7H-3-[5-methyl-1 -(4-methylphenyl)-1,2,3-triazol-4-yl]-6-substit uted-s-triazolo[3,4-b]-1,3,4-thiadiazines and their structures are establis hed by elemental analysis, MS, IR and H-1 NMR spectral data.
