Modification of MnFe2O4 surface by Mo (VI) pyridylimine complex as an efficient nanocatalyst for (ep)oxidation of alkenes and sulfides

ZnO–TiO2 Nanoparticles Coated by the Dioxomolybdenum (VI) bis-Schiff Base Complex for Catalytic Oxidation of Sulfides

“…Also, the immobilized oxodiperoxomolybdenum diSchiff base complex on ionic liquid-modified SBA-15 assigned high catalytic activity, referring to the effect of the ionic liquid-modified SBA-15 on the reactivity of the Mo–complex catalyst for the oxidation of MePhS, as shown in Table S3 . Another reported catalyst of the Mo (VI) pyridylimine complex immobilized on the MnFe 2 O 4 surface was recently reported, which represented high catalytic effectiveness, however, with high loaded amount of the catalyst . The oxodiperoxo molybdenum complex was supported on Cr-MOFs, as [MoO­(O 2 ) 2 @En/MIL-100­(Cr)], which is utilized for the oxidation of sulfides, in which Cr-MOFs enhanced the catalytic reactivity of the oxodiperoxo molybdenum complex for the oxidation of MePhS with less required temperature and time.…”

“…Carrasco et al reported the chemo-selective oxygenation of organic sulfides to the corresponding sulfoxides using H 2 O 2 in the presence of immobilized oxodiperoxomolybdenum Schiff base complex SBA-15. The successful (ep)­oxidation of sulfides and alkenes by dioxomolybdenum (VI) pyridyl–Schiff base complex-coated nanoparticles of MnFe 2 O 4 was reported recently by Bouzari et al The immobilized cis -MoO 2 -complex on Cr-MOFs for high catalytic efficiency toward selective thioether oxidation was presented by Rostamnia and Mohsenzad, in which the catalytic performance required long running time. Moreover, the immobilized Mo­(VI)–Schiff base complexes on the surface of high magnetic Fe 3 O 4 nanoparticles have been shown to exhibit high reactivity in the selective sulfide oxidation processes .…”
