Abstract
Thiocarbamoylation of CH-Acidic Arylsulfinyl and Arylthio Compounds Reaction 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).
