The mechanism of deoxygenation reaction of oxaziridine with trivalent phosphine was kinetically examined by changing substituents, solvents, and temperatures. The reaction proceeds through an attack of phosphine on oxgen in a concerted manner rather than on nitrogen or carbon, eventually producing the corresponding imine and phosphine oxide. The mechanism of the title reaction was compared with those of similar deoxygenations of epoxide and thioepoxide.
