Disulfur dichloride - Wikipedia

It should be emphasized that all the sulfonium salts (5-6), especially the 2-chloroethyl compound, possess noteworthy toxicity. This toxicity may be due to the decomposition of the sulfonium salts under physiological conditions to form alkylating moieties. The conversion of these sulfonium salts to reactive species is considerably slower than for sulfur mustard. The chemical reactions of the sulfonium salts have been studied in detail, but it is not known whether they are actually formed in vivo . It is certainly possible that such toxic products might be formed on moist areas of the skin, which is consistent with the high susceptibility of these regions to the vesicant action of sulfur mustard. The physiological effects and toxicities of the sulfonium salts need to be investigated, since the proposed mechanism of the cytotoxicity of sulfur mustard is based on the simplified SN1 hydrolysis and is not fully understood.

Sulfur dichloride - Sciencemadness Wiki

To ensure pure first-order kinetics, sulfur mustard is predissolved in a polar organic solvent, and its concentration is kept low in solution so that the rate of the reverse reactions become negligible compared to kw. The overall reaction—the formation of dithioglycol and 2 HCl—can be described as a quasi-monomolecular process with first-order kinetics. The rate constant for the hydrolysis of sulfur mustard, as determined by acid production, is markedly dependent on temperature and the presence of chloride ion, which retards the hydrolysis rate without altering the reaction products. The retardation of hydrolysis by added chloride is consistent with the reversibility of the activation step to cyclic sulfonium ion. The rate of hydrolysis is not pH dependent and is not altered by metal ions.

Also called ETHYLENE DICHLORIDE, or 1,2-DICHLOROETHANE, a colourless, toxic, volatile liquid belonging to the family of organic halogen compounds and having an odour resembling that of chloroform. It was formerly important as a solvent and as a raw material for making ethylene glycol and polysulfide rubbers, but now it is principally used for making vinyl chloride and as a component of tetraethyllead anti-knock formulations for gasoline. Ethylene chloride is produced by the reaction of ethylene and chlorine; it is denser than water and practically insoluble in it. It is an effective solvent for fats, waxes, greases, and numerous other organic compounds, but its use as a solvent has been largely discontinued in favour of tetra-chloroethylene.

Disulfur dichloride can also be used to synthesize -dithiobissulfoximines, to synthesize macrocyclic, polysulfur compounds, and is part of an extremely powerful chlorinating agent for perchlorination of aromatic systems (see also and ). It is also a reagent for the synthesis of aranotins, a small group of sulfur-bridged diketopiperazines, and it was tried in conjunction with sulfur dichloride for one-step episulfide synthesis.

Sulfur dichloride - an overview | ScienceDirect Topics

The synthesis and chemistry of sulfur mustard, or mustard gas, have been studied and reviewed extensively. Chemical and physical data regarding sulfur mustard were presented in . Meyer first prepared pure sulfur mustard by the reaction of thiodiglycol with phosphorus trichloride (5-2). Thiodiglycol was prepared by the reaction of 2-chloroethanol with potassium sulfide (5-1):

Studies on the mechanism and kinetics of the hydrolysis of sulfur mustard have shown that the first step in this reaction is the formation of a transient cyclic sulfonium cation, which then reacts quickly with water to form 2-chloroethyl-2-hydroxysulfide and a hydrogen ion. The reaction sequence is repeated to give dithioglycol (5-5):
