S. Bahceci et al., REACTIONS OF 4-AMINO-4,5-DIHYDRO-1H-1,2,4-TRIAZOL-5-ONES AND 4-AMINO-4H-1,2,4-TRIAZOLES WITH SOME CARBOXYLIC-ACID ANHYDRIDES, Turkish journal of chemistry, 22(3), 1998, pp. 237-241
lorophthalimido-4,5dihydro-1H-1,2,4-triazol-5-ones (2) and naphthalimi
do)-4,5-dihydro-1H-1,2,4-triazol-5-ones (3) were synthesized from the
reactions of (aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1) wi
th tetrachlorophthalic anhydride and 1,8-naphthalic anhydride, respect
ively. In addition, the reactions of 4-amino-4H-1,2,4-triazoles (4) wi
th succinic anhydride and phthalic anhydride were studied.
