Modern Trends in the Synthesis of Disulfides: From Metal-Containing Catalysts to Nonmaterial Reagents (Review)

Abstract

The modern trends in the development of synthetic approaches to the preparation of organic symmetrical and unsymmetrical disulfides are reviewed. The main trend in the synthesis of disulfides is the transition from the reactions involving metal-containing catalysts to the use of physical methods for the activation of sulfur substrates. The main attention is given to the works published since 2013 to the present time and devoted to the synthesis of disulfides in the presence of transition and nontransition metal complexes and organic and inorganic oxidants, as well as under the electric current action and photo- or microwave irradiation.
