Ei reaction of sulphilimines and related compounds

Ei reaction of tertiary amine oxides, i.e. the Cope elimination and that of sulphoxides, are briefly reviewed. N-p-Tosylsulphilimines also undergo facile Ei reaction upon heating and the stereospecificity of the reaction is better than that of the corresponding sulphoxides and even somewhat better than that of the tertiary amine oxides.A general outlook on research on the Ei reactions of sulphilimines and the mechanism of the reaction are discussed in comparison with those of similar Ei reactions which proceed via 5-membered cyclic transition states.
