• We have examined the kinetics of the reactions between <I>N</I>-sulfmylanilines and formic acid. The reactions follow this rate equation; rate=<I>k</I>[R–C<SUB>6</SUB>H<SUB>4</SUB>–NSO][HCOOH]. The kinetic runs were made over a wide temperature range (40–90°C) in order to obtain the values of the activation energy. The values for the reactions of <I>N</I>-sulfinylaniline, <I>N</I>-sulfinyl-<I>p</I>-toluidine, and <I>N</I>-sulfinyl-<I>p</I>-chloroaniline with formic acid are 14.6, 15.1, and 10.1 kcal/mol respectively. The reaction mechanism is discussed by means of their NMR spectral data.
