Palladium(II)‐Catalyzed Oxidation of Primary Amines by Bromamine‐T in Alkaline Medium: A Kinetic and Mechanistic Study

Abstract

Oxidations of n‐propyl, n‐butyl and n‐hexylamines by bromamine‐T (BAT), catalyzed by Pd(II), in alkaline medium have been kinetically studied at 30 °C. The reaction rate shows a first‐order dependence on [BAT], a fractional‐order dependence each on [NaOH] and [Pd(II)], and an inverse fractional‐order dependence on [Cl–]. The reaction rate is independent of [amine]. The addition of the reduction product of BAT, p‐toluenesulfonamide, and the variation of dielectric constant of the solvent have no effect on the rate. The catalytic constants were calculated at different temperatures. Activation parameters were evaluated.
