Abstract

In order to reveal the reactivity of toluenethiols, the hydrogen isotope exchange reaction between one of three toluenethiols (o −,m −, andp −) and poly (vinyl alcohol) labeled with tritium was observed at 50 ≈ 90°C. The reaction was analyzed with both the data obtained and theA″-McKay plot method, and the following has been quantitatively clarified: (1) the reactivity order of toluenethiols is (o −>(m −)>(p −); (2) the temperature dependences of the reactivity of toluenethiols are nearly equal; (3) the reactivity of benzenethiol is considerably decreased by the CH3 group bonded to the ortho position.
