The Oxidation of 1-Thioaroylsemicarbazides
Kurzer, Frederick,Doyle, Kevin M.
, p. 1873 - 1880 (2007/10/02)
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, me
