Synthesis and phase-transfer property of macrocyclic polythiaether sulphoxides

Abstract

New macrocyclic polythiaethers with alkylthio side chains have been prepared in good yields starting from 2,6-dithiaspiro[3.3]heptane. The corresponding polysulphoxides were also prepared by the general oxidation method. The macrocyclic polythiaether sulphoxide with benzylsulphinyl side chains was found to be an excellent phase-transfer catalyst which promotes alkylation of benzyl methyl ketone with alkyl halides in a liquid-liquid two-phase system.
