The oxidation of 1-thioaroylsemicarbazides
Abstract
Oxidation of 1-thioaroylsemicarbazides by bromine or hydrogen peroxide yields bis(C-aryl-N-ureido)formimidoyl disulphides. As a novel class of the generally labile di-imidoyl disulphides, such products display unusual stability; however, upon acylation, methylation, and acid or alkaline hydrolysis they are cleaved at their disulphide bond, to give the same products as their thioaroyl precursors.
