抄録

The substituent effects on solvolysis of 2-aryl-2-(trifluoromethyl)ethyl <I>m</I>-nitrobenzenesulfonates, in acetic acid and in 80% aqueous trifluoroethanol, were analyzed by Yukawa-Tsuno equation. The resonance demands (<I>r</I> = 0.77 in acetic acid) were larger than that of standard aryl-assisted solvolysis by 0.2. This enlargement should depend on a destabilization of aryl-assisted transition-state by an electron-withdrawing trifluoromethyl group.
