    Description / Table of Contents: Synthesis of N-(Hexafluoroisopropylidene)benzenesulfinamides and Their Reactive Behaviour Towards NucleophilesSulfinamides react with hexafluoroacetone or 1,3-dichloro-1,1,3,3-tetrafluoroacetone to yield the N-[2,2,2-trifluoro-1-hydroxy-1-(trifluoromethyl)ethyl]-and N-[2-chloro-1-(chlorodifluoromethyl)-2,2-difluoro-1-hydroxyethyl]sulfinamides 4 and 5, respectively. The compounds 4 can be transformed by bis(trifluoroacetic) anhydride or phosphoryl chloride/pyridine into the N-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]sulfinamides 6. Alcohols, thio alcohols or amines are added to the hetero-1,3-dienes 6 in 1,2-position.  -  The spectral data of the new compounds are described.
    Notes: Sulfinsäureamide reagieren mit Hexafluoraceton oder mit 1,3-Dichlor-1,1,3,3-tetrafluoraceton zu den N-[2,2,2-Trifluor-1-hydroxy-1-(trifluormethyl)ethyl]-oder N-[2-Chlor-1-(chlordifluormethyl)-2,2-difluor-1-hydroxyethyl]sulfinsäureamiden 4 bzw. 5. Die Verbindungen 4 werden durch Bis(trifluoressigsäure)anhydrid oder Phosphorylchlorid/Pyridin in die N-[2,2,2-Trifluor-1-(trifluormethyl)ethyliden]sulfinsäureamide 6 übergeführt. Die Hetero-1,3-diene 6 nehmen Alkohole, Thioalkohole oder Amine unter 1,2-Addition auf.  -  Die spektroskopischen Daten der neuen Verbindungen werden angegeben.
