• The reaction of <I>N</I>phenylsulfonyl-3,5-di-<I>t</I>-butylphenylaminyl radical (<B>2</B>) with unsaturated aromatic and aliphatic hydrocarbons has been carried out in degassed benzene at 75°C. The reactions of <B>2</B> with unsaturated aromatic hydrocarbons gave 1:1, 1:2, and 2:1 adducts of <B>2</B> and the hydrocarbons in fair to good yields. On the other hand, in the reactions of <B>2</B> with unsaturated aliphatic hydrocarbons, hydrogen-abstraction by <B>2</B> from the hydrocarbons was the major reaction. In the reaction with 2-methylpropene, a product indicating the addition of <B>2</B> to 2-methylpropene was isolated in a 16% yield. On the basis of these results the reactivity of <B>2</B> is discussed and compared with that of structurally related <I>N</I>(4-chlorophenylthio)-3,5-di-<I>t</I>-butylphenylaminyl radical.
