On September 30, 2021, Garg, Anirban; Borah, Nobomi; Sultana, Jasmin; Kulshrestha, Akshay; Kumar, Arvind; Sarma, Diganta published an article.Formula: C9H9N3 The title of the article was Silica immobilized copper N-heterocyclic carbene: An effective route to 1,2,3-triazoles via azide-alkyne cycloaddition and multicomponent click reaction. And the article contained the following:
A new silica supported copper N-heterocyclic carbene (Cu-NHC@SiO2) complex is prepared and characterized by SEM (SEM), energy dispersive X-ray spectroscopy (EDX) and XPS analyses. This complex is an efficient and easily retrievable catalyst for 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition reaction as well as one-pot reaction using arylboronic acids. This catalytic system is also suitable for synthesis of 4-aryl-NH-1,2,3-triazoles from diverse benzaldehydes. Further, the catalyst can efficiently be recycled up to fifth cycle for all the three methods of 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition and multi-component reactions. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Formula: C9H9N3
