for the synthesis of aryl-3,5-bis(trifluoromethyl)-4H-1,2,4-triazoles is disclosed via the nucleophilic intramolecular cyclization reaction of trifluoromethylated amidrazone and 2,2,2-trifluoroacetic anhydride. The trifluoromethylated amidrazone intermediates used in this project are synthesized from the reaction of N-aryl-2,2,2-trifluoroacetimidoyl chloride derivatives and hydrazine hydrate at ambient
通过三氟甲基化脒腙和 2,2 的亲核分子内环化反应,公开了一种新型、高效、无溶剂合成芳基-3,5-双(三氟甲基)-4 H -1,2,4-三唑的方法,2-三氟乙酸酐。本项目使用的三氟甲基化脒腙中间体是由N-芳基-2,2,2-三氟乙酰亚胺酰氯衍生物与水合肼在常温下反应合成,收率极佳。
