Tetrakis(alkylsulphinylmethyl)methanes have been shown to serve as good phase-transfer catalysts which accelerate SN2 type displacements of octyl bromide with various nucleophiles (thiocyanate, cyanide, phenoxide, and thiolate) in solid-liquid two-phase systems.Alkylation of phenylacetonitrile with alkyl halides has also been carried out in liquid-liquid two-phase systems in the presence of the above sulphoxides to afford the corresponding mono-alkylated products in high yields.

New macrocyclic polythiaethers with alkylthio side chains have been prepared in good yields starting from 2,6-dithiaspiroheptane.The corresponding polysulphoxides were also prepared by the general oxidation method.The macrocyclic polythiaether sulpho

Tetrakis(alkyl-sulfinylmethyl)methanes serve as highly efficient phase transfer catalysts in SN2 type displacement reactions of n-octyl bromide with a few nucleophiles.

Synthesis of a new macrocyclic polythiaether (12) which is easily obtained in a good yield via 2,6-dithia-4-spiroheptane (6) is described.Several reactions of pentaerythrityl bromide (1) with nucleophiles and a few ring opening reactions of 6 with methyl iodide are also described.
