A number of symmetrical 3,5-disubstituted-4H-1,2,4-triazoles have been synthesized in good yields by deamination of the corresponding 4-amino-1,2,4-triazoles via reductive diazotation of these amino compounds in the presence of hypophosphorous acid. Analytical, spectral data and theoretical calculations confirmed the structures of the new triazole derivatives.
通过将相应的4-氨基-1,2,4-三唑经氨基化合物的还原重氮化反应,将相应的4-氨基-1,2,4-三唑进行脱氨基反应,以高收率合成了许多对称的3,5-二取代-4 H -1,2,4-三唑。次磷酸的存在。分析,光谱数据和理论计算证实了新的三唑衍生物的结构。
