    Description / Table of Contents: Fluorine-substituted 1,2-Thiazetan-3-one 1-Oxides by Reaction of Bis(trifluoromethyl)ketene and N-Sulfinylamines4,4-Bis(trifluoromethyl)1,2-thiazetan-3-one 1-oxides 3a-e are prepared by the reaction of bis(trifluoromethyl)ketene (1) with some N-sulfinylamines 2a-e. Under hydrolytic conditions the amides of 3,3,3-trifluoro-2-(trifluoromethyl)propionic acid 4a-e are formed, which are also obtained from 1 and the corresponding amines, especially C6F5NH2 and CF3NH2. 3e undergoes an unexpected thermolysis at room temperature with partial formation of trifluoromethyl isocyanate (5) and bis(trifluoromethyl)methylene sulfoxide (6).
    Notes: Die 4,4-Bis(trifluormethyl)-1,2-thiazetan-3-on-1-oxide 3a-e werden durch Reaktion von Bis(trifluormethyl)keten (1) mit einigen N-Sulfinylaminen 2a-e dargestellt. Unter Hydrolysebedingungen bilden sich die Amide der 3,3,3-Trifluor-2-(trifluormethyl)propionsäure 4a-e, die auch aus 1 und den entsprechenden Aminen, insbesondere C6F5NH2 und CF3NH2, erhalten werden. 3e erfährt eine unerwartete Thermolyse bei Raumtemperatur unter teilweiser Bildung von Trifluormethylisocyanat (5) und Bis(trifluormethyl)methylensulfoxid (6).
