Sumario:[Image: see text] Cetrimonium bromide (CTAB)-coated water disperse magnetically separable nanocatalysts CTAB/Fe(3)O(4)@dopa@ML (M = Fe or Mn, L = cyclohexane-1,2-diylbis(azanylylidene)bis(methanylylidene)bis(2,4-diXphenol; X = Cl, Br, and I) have been synthesized using a simple synthetic strategy. This approach provides a new fruitful strategy to reduce the leaching of the active metal complex from the catalyst surface to the aqueous media. The synthesized catalysts have been found to be excellent for oxidation of alcohols in aqueous medium at room temperature. A probable catalytic pathway involving the generation of hydroperoxo intermediates has been assumed, and these intermediates have been characterized using density functional theory and several spectroscopic techniques. It is worthy of mention that the synthesized CTAB-coated magnetically separable nanocatalysts can be magnetically recovered from the aqueous reaction mixture after more than five cycles, which renders this approach as a sustainable and accessible one.
