During the past few decades, fabrication of multistep fluorescence-resonance energy transfer (FRET) systems has become one of the most attractive topics within supramolecular chemistry, chemical biology, and materials science. However, it is challenging t

A highly selective catalytic oxidation system has been developed for the conversion of sulfides into the corresponding sulfoxides using urea-hydrogen peroxide as stoichiometric oxidant in the presence of a catalytic quantity of diphenyl diselenide.

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

While most organic sulfides were not oxidized by dimethyl sulfoxide (DMSO), the alkyl 2-chloroethyl sulfides and bis(2-chloroethyl) sulfide slowly reacted with DMSO to produce the corresponding sulfoxides at 25-70 deg C under nitrogen.The mechanism of the oxidation is proposed to involve nucleophilic substitution by DMSO followed by neighboring sulfur participation to form a transient sulfonium ion with a four-membered ring structure.The sulfonium ion intermediate rapidly reacts with the chloride ion to produce 2-chloroethyl sulfoxides. 2-Hydroxyethyl sulfoxides were also produced, probably due to the presence of a trace amount of water in the DMSO.This reaction demonstrates, for the first time, the unique reactivity of 2-chloroethyl sulfides in DMSO.

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.
