A novel heterogeneous method for efficient oxygenation of olefins to epoxides and saturated hydrocarbons to the related ketones using tetrabutylammonium peroxomonosulfate (n-Bu4NHSO5) in neat water catalyzed by Fe(TPP)Cl and Fe(TDCPP)Cl complexes as water-insoluble catalysts has been developed. The...
Rezaeifard, A.; Jafarpour, M.; Naeimi, A.; Kaafi, S. A novel strategy for clean and selective oxygenation of hydrocarbons with n- Bu4NHSO5 in neat water catalyzed by recyclable water-insoluble iron (III) tetraphenylporphyrins. Catal. Commun. 2011, 12, 761-765....
These porphyrins were used as catalysts in the epoxidation of various alkenes with tetra-n-butylammonium hydrogen monopersulfate (n-Bu4NHSO5) as the oxidant and imidazole as the axial base. The following order of catalytic activity was obtained: TPPMnOAc u2265 T(2,3-OMeP)PMnOAc > T(4-OMeP...
