A novel synthesis of cyclic polythioethers using liquid-liquid phase-transfer catalysis

The synthesis of cyclic polythioethers has been achieved by the reactions of dithiols with alkyl dihalides. Thiols are not only hard to handle owing to their unpleasant smell, but also they are easily oxidizable, thus it is not easy to obtain various dithiols. However, we have developed a procedure for the preparation cyclic polythioethers by the reaction of dithioiminium salts with alkyl dihalides using phase-transfer catalyst without the use of dithiols, and have examined the ion recognition of these compounds.

A Novel Redox Reaction of the Disulphide Dication Salt (R2S+-+SR2*2X-) with Carbanions and Alkoxides

The disulphide dication salt, 1,5-dithioniabicyclooctane bis(trifluoromethanesulphonate) (1) was reduced upon treatment with carbanions or alkoxides; it did not deprotonate.

A New Mode of Aromatic Substitution and Redox Reaction of Substituted Benzenes with Disulfide Dication: 1,5-Dithioniabicyclooctane Bis(trifluoromethanesulfonate)

Disulfide dication was found to react with several aromatics to give either the substitution or redox products.The rection mode depends remarkably on the oxidation potential of the aromatics.

A new preparative method, characterization, and reactivity of disulphide dication salts of cyclic bis-sulphides: R2S-SR2· 2CF3SO3-

The reaction of 1,5-dithiacyclo-octane 1-oxide with trifluoromethanesulphonic anhydride affords the corresponding disulphide dication as a stable crystalline salt which serves as an oxidizing agent in the oxidation of 1,2-diphenylhydrazine; the disulphide dication of 1,4-dithiane has also been isolated.
