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

2-Aryl-Δ-2-1,3,4-oxadiazoline-5-thione derivatives 2 were synthesized and their uv and ir spectra were studied. Correlation between σ-Hammett constants of aryl substituents and the differences in absorption maxima (Δv = v1-v2 in kK) of the electronic spectra of the deprotonated species were also evaluated. A new method for the synthesis of the 2-(amino)aryl derivatives 2v,w,x is also reported.
二十四2-芳基Δ- 2 -1,3,4-恶二唑啉-5-硫酮衍生物2的合成和它们的UV和IR光谱进行了研究。还评估了芳基取代基的σ-Hammett常数与去质子化物种的电子光谱的吸收最大值差异(Δv= v 1 -v 2以kK为单位)之间的相关性。还报道了合成2-(氨基)芳基衍生物2v,w,x的新方法。
