Abstract Reactions of morpholine in dimethyl sulphoxide at unsubstituted ring positions of 1, 3, 5-trinitrobenzene, and phenyl 2, 4, 6-trinitrophenyl ether, yield anionic σ-adducts via zwitterionic intermediates. Reactions at the 1-position of phenyl 2, 4, 6-trinitrophenyl ether, phenyl 2, 4-dinitronaphthyl ether, and phenyl 2, 4-dinitrophenyl ether result in substitution of the phenoxy groups. In both these reaction types proton-transfer is rate-limiting. ...
