A series of 1-substituted 1H-1,2,3,4-tetrazole compounds have been synthesized in good yields from amines, triethyl orthoformate, and sodium azide through the catalyzed reaction with Yb(OTf)3. Some of the 1-susbstituted 1H-1,2,3,4-tetrazole compounds showed strong phytocidal activity. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
通过与 Yb(OTf)3 的催化反应,以胺、原甲酸三乙酯和叠氮化钠为原料,以良好的收率合成了一系列 1-取代的 1H-1,2,3,4-四唑化合物。一些 1-取代的 1H-1,2,3,4-四唑化合物显示出很强的杀植物活性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
