A novel SBA-15 supported catalyst PdLn@SBA-15 containing a 2-pyridyl-1,2,3-triazole ligand framework was prepared via a “click” route, in which the click-triazole acted as both a stable linker and a good chelator. The catalyst was characterized and applied for the aerobic oxidation of alcohols, and the product was obtained in up to 98% yield.
A series of novel bis(NHC) Cu(i) catalysts enables the production of triazoles with different substitution patterns and bioconjugation via “click” chemistry under homogeneous and/or heterogeneous catalytic conditions in aqueous media.
