Abstract Some new heterocyclic systems 2-9 were obtained through the reaction of 4-amino-5-mercapto-3-trifluoromethyl-1,2,4-triazole (1) with ylidenemalononitriles, 1,3-diketones, halonitriles, active nitriles, aromatic aldehydes or ketones. Also spiro systems 10-12 were achieved in one pot synthesis by addition of compound 1 to isatine, cycloalkanones or ylidenenitriles followed by cyclization. The
