On December 23, 2009, Kuang, Chunxiang; Kong, Linglei published a patent.Recommanded Product: 4-(p-Tolyl)-1H-1,2,3-triazole The title of the patent was 5-Halogenated-4-aryl-1H-1,2,3-triazole compound and its preparation process. And the patent contained the following:
The invention relates to the method for preparing 5-halogenated-4-aryl-1H-1,2,3-triazole compounds of formula I. Compounds of formula I wherein the dotted bond is a single bond or a double bond; Ar is Ph and 4-methylphenyl; X is halo; R is absent and H; are claimed. Compounds of formula I were prepared via halogenation of 4-phenyl-1H-1,2,3-triazole or 4-(4-methylphenyl)-1H-1,2,3-triazole. The N-halogenated agent is selected from N-bromosuccinimide, N-iodosuccinimide, or N-chlorosuccinimide. The process has the advantages of simple operation, mild reaction condition, low cost, wide prospect of application, and suitability for industrialized production, and the title compound can be used as important intermediate compound for synthesis of medicine. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Recommanded Product: 4-(p-Tolyl)-1H-1,2,3-triazole
The Article related to aryl triazole halogenation, halo aryl triazole preparation, Heterocyclic Compounds (More Than One Hetero Atom): Other 5-Membered Rings, Two Or More Hetero Atoms and other aspects.Recommanded Product: 4-(p-Tolyl)-1H-1,2,3-triazole
