• An ESR spectroscopic investigation of <I>N</I>-(2,4,6-trimethyl-, trimethoxy-, triisopropyl-, and tri-<I>t</I>-butylphenyl)<I>N</I>-(aiylthio)aminyls (<B>2</B>), Ar\dotNSAr′, is described. The aminyls are generated from the corresponding <I>N</I>-arylarenesulfenamides, ArNHSAr′, by hydrogen-abstraction, the <I>a</I><SUB>N</SUB> values of which are 9.10–12.30 G and the <I>g</I>-values 2.0056–2.0067. On the basis of the ESR parameters the conformations for <B>2</B> have been discussed. Decay kinetic studies on <B>2</B> were conducted in benzene, and <B>2</B> were found to be persistent aminyls—particularly the <I>t</I>-butylsubstituted aminyl, <I>N</I>-(2,4,6-tri-<I>t</I>-butylphenyl)-<I>N</I>-(4-nitrophenylthio)aminyl.
