                                    2-or 3-cyanoalkyl-4-amino-5-aryl-1,2,4-triazoles were synthesized by condensing several 3-mercapto-4-amino-5-aryl- 1,2,4-triazoles with halonitriles Cl(CH2)(n)CN where n=1-3. These reactions afforded new compounds and the use of different bases aids in accomplishing eHclusive N or S alkvlation at 2 or 3 position of the triazoles,
