  • Patent number: 5621118
    Abstract: A process for oxidizing a substrate susceptible to nucleophilic oxidation by reacting a bicaroate or monopersulfate solution with the substrate is disclosed. In one aspect, the substrate is introduced into the reaction mixture in an inert carrier gas, which can also serve to sweep the product out of the mixture. In a second aspect the oxidation solution is obtained by a two stage neutralization of a Caro's acid solution, the first stage to e.g. 0.5 to 2.0 and the second stage to about 7 to 9. In preferred embodiments, the substrate is introduced into partially neutralized Caro's acid, and the second stage neutralization in the presence of the substrate is most preferably carried out with an alkali salt such as sodium bicarbonate. The process can employ relatively low ratios of substrate: Caro's acid oxidant and homogeneous reaction conditions. The process is particularly useful for preparing dioxiranes from ketones.
