Some derivatives of 1,1'-thiobis(2-chloroethane) (sulphur mustard) have been synthesized for use as reference compounds in a wide range of studies embracing analysis, metabolism, environmental degradation and decontamination.Compounds include products formed by hydrolysis, substitution and elimination reactions and their oxidised sulphoxide and sulphone analogues.A comprehensive series of methylthio, methylsulphinyl and methylsulphonyl derivatives has been synthesised in support of metabolic studies. Key words: Thiobis(2-chloroethane) and derivatives; analysis; metabolism; environmental degradation; decontamination
ANODIC OXIDATION OF 1,n-HALO(ALKYLTHIO)ALKANES AND 1,n-CHLORO(ALKYLSULFINYL)ALKANES

Anodic oxidation of 1,n-halo(alkylthio)alkanes n-S-R, X=Cl, Br, I> and 1,n-halo(alkylsulfinyl)alkanes n-S(O)-R> was studied by cyclic voltammetry in anhydrous acetonitrile and by controlled potential electrolyses.The ease of sulfur oxidation was not affected by the alkyl substituents R or the number of methylene groups n in compounds with n>2.The oxidation of the 1,2-halo(alkylthio)ethanes (n=2) occurred at slightly higher potentials.The peak potentials decreased slightly in the order Cl>Br>I which is probably due to the electronegativity of the halogen atoms.The investigated anodic oxidation was shown to be a two electron irreversible process.Electrolyses in aqueous acetonitrile led to the corresponding sulfoxides and sulfones in good yields.

It was confirmed that the cathodic crossed coupling of acetone with unsaturated compounds in aqueous sulfuric acid could proceed smoothly, when the compounds which had radical-acceptable double bonds and were adsorbed on a mercury cathode were used.From this fact, it was concluded that the coupling occurs via the addition of a radical intermediate formed by the one-electron reduction of acetone to the double bonds on the cathode surface.Possibility of the addition of an anionic intermediate derived from acetone was excluded by no occurrence of the coupling of acetone with a polar acetylenic triple bond compound adsorbed on the cathode.
