Synthesis of α-Chlorothiosulfenyl Chlorides. A New Class of Reactive Organosulfur Compounds

10.1021/jo00342a036

The research focused on the synthesis and investigation of a new class of reactive organosulfur compounds known as α-chlorothiosulfenyl chlorides (R2C(Cl)SSCl), which were derived from the reaction of various aromatic and aliphatic thiones with sulfur dichloride in dry carbon disulfide. The study aimed to explore the potential of these compounds and understand the mechanisms involved in their transformations. The researchers found that the reaction of α-chlorothiosulfenyl chlorides with triphenylphosphine regenerates the thiones, accompanied by the corresponding ketones. Key chemicals used in the process included sulfur dichloride, carbon disulfide, thiones such as thiobenzophenone, xanthione, and various other aromatic and aliphatic thiones, as well as triphenylphosphine. The conclusions drawn from the research highlighted the formation of α-chlorothiosulfenyl chlorides and their potential synthetic utility, noting their unusual reactivity with multiple electrophilic sites and the complexity of the products formed upon reaction with triphenylphosphine.
