Influence of Nitrogen Bases on Epoxidation of Cyclooctene with Sodium Periodate Catalysed by Manganese(III) Porphyrins
Effects of imidazoles and substituted pyridines and pure s-donors on the oxidation of cyclooctene with NaIO4 by 5,10,15,20-tetraphenylporphyrinato-manganese(III) acetate, Mn(TPP)OAc, and 5,10,15,20-Tetramesitylporphyrinato-manganese(III) acetate, Mn(TMP)OAc, catalysts in CH2Cl2-H2O solvent are studied. Coordination of the nitrogen donors to the Mn...

متن کاملMagnetic nanoparticles containing Manganese salophen complex as an selective and recyclable catalyst for epoxidation of alkenes
A magnetically recoverable catalyst consisting of Mn (III) salophen complex was prepared. The synthesized catalyst was characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and Fourier transform infrared (FT-IR). The immobilized catalyst was shown to be an ef...

متن کاملThe rate-determining step in the epoxidation of alkenes by the cytochrome P-450 model manganese(III) porphyrin/hypochlorite
Using low-temperature trapping experiments with 1 ,l-diphenyl-2-picrylhydrazine moni tored by UV/Vis spectroscopy, it is shown that the rate-determining step in the epoxidation of alkenes by hypochlorite, catalysed by manganese(III) porphyrins, involves the formation of the active oxo-manganese species [(P)MnO]+.
