Abstract

Tduoromethanesulphonanilide was prepared by the action of aniline on the anhydride or the acid chloride. This anilide and the analogous amide had remarkable acidic properties; because of the powerful negative inductive effect of the trifluoromethanesulphonyl group, and possibly the negative hyperconjugative effect of the trifluoromethyl group, they were stronger acids than carbonic acid, and on titration with alkali gave end-points between pH ...
