Unexpected Reaction Pathways Leading to Thiodiglycol during the Degradation of Long-Chain Sulfur Mustards

Degradation of long-chain sulfur mustards with various commercial decontaminants unexpectedly forms thiodiglycol (TDG) through unreported reaction pathways. Chemical warfare agents (CWAs) degradation products have to be unambiguously related to their reference compounds in order to fulfill international verification protocols. Thus, the formation of TDG using water-based decontaminants introduces an uncertainty in the origin of this chemical that has been systematically used to unambiguously demonstrate the presence of yperite in environmental and biomedical samples. Therefore, these novel and unprecedented degradation pathways will result either in modifications of the international verification protocols for forensic purposes or in the exclusion of TDG as an exclusive marker of yperite.

Polythiaether compounds and their use as corrosion inhibitors

The corrosion of metals in contact with aqueous alkanolamine solutions in acid gas removal units is inhibited by adding to the alkanolamine solution a corrosion inhibiting amount of a polythiaether compound.

Hydrolysis and oxidation products of the chemical warfare agents 1,2-Bis[(2-chloroethyl)thio]ethane Q and 2,2′-Bis(2-chloroethylthio) diethyl ether T

Syntheses of diols of structure [HOCH2CH2S] 2(CH2)n in 86-95% yield from the sodium salt of 2-mercaptoethanol and Br(CH2)nBr (n = 1 to 5) or in 60-90% yield from 2-chloroethanol and NaS(CH2)nSNa (n = 2 to 5) are described. The diol [HOCH2CH2SCH 2CH2]2O was prepared in 82% yield from the sodium salt of 2-mercaptoethanol and [ClCH2CH2] 2O, and in 88% yield from 2-chloroethanol and [HSCH 2CH2]2O. Mono- and bis-sulfoxides and bis-sulfones of these species were prepared in generally high yield by treatment with an equivalent of KIO4 in aqueous methanol, two equivalents of NaIO4 in aqueous methanol, or four equivalents of H2O2 in trifluoroacetic acid respectively. The compounds are important analytical standards for investigating the fate of the chemical warfare agents sesquimustard Q and oxygen mustard T in environmental samples.

Substituted diether diols by ring-opening of carbocyclic and stannylene acetals

Reduction of malonaldehyde bis(ethylene and propylene acetals) with borane or monochloroborane produces diether diols 1 and 2 in high yield. Similar reduction of glyoxal his(ethylene acetals) has only limited utility for the preparation of tetrasubstituted triethylene glycols 3. Organotin chemistry is complementary: stannylene acetals prepared from disubstituted vicinal diols can be alkylated with half an equivalent of 1,2-dibromoethane to produce tetrasubstituted triethylene glycols 3, or with two equivalents of 2-chloroethanol to produce disubstituted triethylene glycols 4.

Synthesis of certain multidentate benzimidazole-derived ligands

Synthetic procedures are described for obtaining various multidentate ligands incorporating benzimidazole moieties.The benzimidazoles were obtained by the condensation of acids with o-phenylenediamines.Syntheses are reported for N,N-bis(1-methylbenzimidazol-2-ylmethyl)amine (2), N,N'-bis(1-methylbenzimidazol-2-ylethyl)ethylenediamine (5), N,N,N',N'-tetrakis(benzimidazol-2-ylmethyl)-1,2-diaminocyclohexane (6), N,N,N',N'-tetrakis(4-methylbenzimidazol-2-ylmethyl)-1,2-diaminocyclohexane (7), HOOC-(CH2)m-S-CH2-CH2-S-(CH2)n-S-Ch2-CH2-S-(CH2)m-COOH , BzIm-(CH2)m-S-CH2-CH2-S-(CH2)n-S-CH2-CH2-S-(CH2)m-BzIm , HOOC-CH2-S-(CH2-CH2-S)4-CH2-COOH (15) and BzIm-CH2-S-(CH2-CH2-S)4-CH2-BzIm (16).

A Convenient Synthesis of Substituted Polyether Diols

Alkyl-substituted polyether diols (or polythioether diols), which are potential precursors to substituted crown ethers, are produced in high yield by the selective reductive cleavage of C-O bonds in bis(cyclic acetals) by borane or monochloroborane.
