A new series of tetrahydronaphthalene, isothiachromene, isochromene and isoquinolinederivatives were synthesized by reacting cyclohexylidenemalononitrile with active nitriles, active halo compounds, carbon disulfide, aldehydes, isothiocyanates and isocyanates, respectively.

3-(o-Aminophenyl)-4-amino-5-methylthio-s-triazole 1 was used for the synthesis of some new fused heterocycles 2–6, 9 and spiro systems 7, 8. Diazotization of compound 10 led to the formation of compound 11. Alkylation of compound 11 with chloroacetonitrile gave compound 12. Heterocyclic systems 13–16, 18–20 and spiro compouds 17, 21 were prepared through the reaction of compound 12 with the appropriate
