Facile Synthesis of a Polycatenane Compound Based on Ag-triazole Complexes and Phosphomolybdic Acid for the Catalytic Epoxidation of Olefins with Molecular Oxygen

Abstract: A simple and efficient approach was developed for synthesizing a metal-organic polycatenated compound composed of Ag-triazole complexes and phosphomolybdic acid (PMA) clusters. The hybrid compound, namely {[Ag2(trz)2] [Ag24(trz)18]}[PMo12O40]2 (1) (trz = 1,2,4-triazole), showed high catalytic activity, selectivity and recyclability for the epoxidation of olefins with molecular oxygen as the oxidant and isobutyraldehyde as the co-reagent, and could even work well under ambient conditions. The special polycatena… Show more

“…Instead, a new peak at 1248.9 cm −1 represents the newly formed CN bond, which does not exist in 4-AA or eGDY. [31,32] The N 1s peak of eGDY-Click from X-ray photoelectron spectroscopy (XPS) spectrum can be deconvoluted into three peaks centered at 398.7, 400.0, and 402.1 eV, which are assigned to N = N, NC, and NNN, respectively. [33] They are different from the two peaks (399.3 and 400.7 eV) that represent the azide functional group of 4-AA (Figure 1e).…”
