Redox Systems with Sulphur-Centered Species
The reactions discussed below have been chosen to illustrate the potential behaviour of thiyl radicals, disulphide radical anions and other sulphur-containing reactive intermediates, as oxidizing and reducing agents in inorganic, organic and biological systems. The influence of sulphur-containing species on oxidation-reduction reactions has been recognized for many years. Since the first half of this century the chemical and petroleum industries have used mercaptans for the protection of petroleum products (1932) and the stabilization of chlorinated hydrocarbons, such as carbon tetrachloride (1933), against autoxidation.1 The fundamental role of RSH appears to be that of a scavenger of oxygen and/or an inhibitor of oxidation catalysts.
