Abstract

A series of imines have been oxidized to nitrones in reasonable yields with the permanganate ion under phase-transfer conditions. The influence of the amount of permanganate, solvents, phase-transfer catalysts, and acidity of the aqueous phase on the reaction course have been investigated. It has been found that the presence of water is necessary for the formation of the nitrone. The best phase-transfer catalysts are ...
