Vorona, Svetlana V.; Zevatskii, Yuri E.; Myznikov, Leonid V. published an article in 2019, the title of the article was Zinc (II) Chloride as Phase Transfer Catalyst and as Catalyst of Cycloaddition Azide Ion to Heterocumulenes and Terminal Alkynes in Organic Solvents.Name: 4-(p-Tolyl)-1H-1,2,3-triazole And the article contains the following content:
The system of NaN3-ZnCl2 in organic solvents was effective for azide ion cycloaddition to heterocumulenes and terminal alkynes. The reaction proceeded readily in the case of heterocumulenes, so these transformations fall into the category of click reactions. The study on the reaction mechanism showed that role of zinc salt consists in transferring azide ion to the organic phase and decreasing the energy barrier of nucleophilic addition of azide ion to the unsaturated substrate. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Name: 4-(p-Tolyl)-1H-1,2,3-triazole
The Article related to isothiocyanate sodium azide zinc chloride catalyst cycloaddition, thiotetrazole preparation, carbodiimide sodium azide zinc chloride catalyst cycloaddition, aminotetrazole preparation, terminal alkyne sodium azide zinc chloride catalyst regioselective cycloaddition, triazole preparation and other aspects.Name: 4-(p-Tolyl)-1H-1,2,3-triazole
