✦ Synopsis

The rates of tungsten(VI) catalyzed perborate oxidation of 29 para-, meta-and ortho-substituted anilines in aqueous acetic acid at 35-55ЊC conform to the Exner relationship, also the activation parameters to the isokinetic relationship but not to any of the linear free energy relationships. The results are rationalized.

Tungsten(VI) catalyzes perborate oxidation of S-phenylmercaptoacetic acid. The catalyzed oxidation is first order with respect to the oxidant, independent of [H ϩ ], and displays Michaelis-Menten dependence on [PhSCH 2 COOH] and [W(VI)]. The reaction requires time for equilibration between the oxida
