Many 1,4-dihydropyridines hybrid with 1,2,4-triazole 4a-l were synthesized by the reaction of 5,5′-(2,6-dimethyl-4-phenyl-1,4-dihydropyridine-3,5-diyl)bis(4-amino-4H-1,2,4-triazole-3-thiol) (2) with various substituted aldehydes.

Complexes of 1,2,4-triazole (TR) and 3-amino-1,2,4-triazole (AT) with N2 were studied computationally employing MP2 and B3LYPD3 methods and experimentally by FTIR matrix isolation technique. The results show that both triazoles interact specifically with dinitrogen in several different ways.

Syntheses of substituted‐1,2,4‐triazoles
Journal of Heterocyclic Chemistry, 1992AbstractStarting from the readily available 3‐phenylpropionitrile, 3‐(or 5‐)(2‐phenethyl)‐1,2,4‐triazole3was prepared. Reaction of compounds3with diazomethane afforded 1‐methyl‐3‐(2‐phenethyl)‐1,2,4‐triazole(4)and 1‐methyl‐5‐(2‐phenethyl)‐1,2,4‐triazole(5). Reaction of compound3with methanesulfonyl chloride, benzenesulfonyl chloride orp‐toluenesulfonyl
