Abstract

The ¹³C and ¹⁵N NMR spectra of some ortho-, meta-, and para-substituted dimethanesulphonanilides were recorded. The ¹³C chemical shifts were analysed utilizing substituent chemical shifts for monosubstituted benzenes and by means of the dual substituent parameter (DSP) and DSP-non linear equations. The results indicate that the -N(SO₂Me)₂ moiety is an extremely weak electron donor. The ¹⁵N chemical shifts of the parasubstituted compounds were also analysed by means of DSP equations and the results compared with those of related compounds. An improved method of preparation of dimethanesulphonanilides is given.
