• Studies have been made of the kinetics of the reactions of thiol acids (thiostearic acid and thioacetic acid) with anilines, such as aniline and <I>p</I>-methoxy-, <I>p</I>-ethoxy-, <I>p</I>-methyl-, <I>m</I>-methyl-, <I>p</I>-chloro, <I>m</I>-chloro-, and <I>m</I>-nitrosubstituted anilines, in a chlorobenzene solution. The rate is given by <I>k</I>(RCO–SH) (X-C<SUB>6</SUB>H<SUB>4</SUB>-NH<SUB>2</SUB>). The activation energy for the reaction of thiostearic acid with aniline is 5.3 kcal/mol. The Hammett plots give a straight line, with a value of ρ=−2.40 for the reactions of thiostearic acid or thioacetic acid with the anilines; the mechanism of the reaction of thiol acids with anilines is discussed.
