Os(VIII)-catalysed oxidation of sulfides by sodium salt of N-chlorobenzenesulfonamide

Catalytic activity of Os(VIII) in the oxidation of some twenty organic sulfides with sodium salt of N-chlorobenzenesulfonamide (CAB) has been investigated in alkaline (pH∼8.7) t-butanol–water (1:1 v/v) medium. Significant retarding influence of [OH −] on the reactivity is exhibited. The catalysed re...

Summary:Catalytic activity of Os(VIII) in the oxidation of some twenty organic sulfides with sodium salt of N-chlorobenzenesulfonamide (CAB) has been investigated in alkaline (pH∼8.7) t-butanol–water (1:1 v/v) medium. Significant retarding influence of [OH −] on the reactivity is exhibited. The catalysed reaction is strongly accelerated in the presence of Hg(II). Imperfections are observed in the linear Hammett relationship in the case of –NO 2 substituents.
