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。
