    Notes: Thiocarbamoylation of CH-Acidic Arylsulfinyl and Arylthio CompoundsReaction of arylsulfinyl and arylthio acetonitriles (1) with phenyl isothiocyanate in the presence of sodium hydride and subsequent alkylation lead to the ketene S,N-acetals (3a-h). Using methyl bromoacetate as alkylating agent thiazolidones (4a-c) are formed whereas phenacylbromide gives the 4-hydroxythiazolidines (5a-f). In an analogous way arylthio and arylsulfinyl acetophenones (6) react with phenyl isothiocyanate yielding S,N-acetals (7a-e).

    Dithiocarboxylierung von CH-aciden Sulfoxiden und Thioethern (1992)
    Weinheim : Wiley-Blackwell

    Notes: Dithiocarboxylation of CH-Acidic Sulfoxides and ThioethersReaction of (arylsulfinyl)acetonitriles or (arylthio)acetonitriles 1 (X = SO, S) with carbon disulfide in the presence of sodium hydride and subsequent alkylation yield the open-chain or cyclic ketene S,S-acetals 3 or 4, respectively. Using two equivalents of an α-CH-acidic halo compound as alkylating agent, thiophenes 5 are formed. Treatment of 3a with 2-mercaptoethanol affords the 1,3-oxathiolane 6. The 1H-NMR spectra of phenylsulfinyl-substituted compounds 3b, 4a, 4b, 5a and 6 show a typical AB system for the methylene group caused by the chiral sulfoxide group.
