    Description / Table of Contents: On Reactions of Bis(trifluoromethyl)diazomethane with SulfonylisocyanatesSulfonylisocyanates RSO2NCO (B = F, Cl, CF3) react with (CF3)2CN2 at 100-160°C to give l,2,3-oxathiazole-4-one-2-oxidesWhile the ring IIa is cleaved by methanol (formation of FSO2—NH—C(O)—C(CF3)2OH) with waterThe proton of the compound V might be substituted by metal atoms, especially the silver salt is suitable for the preparation of further 1,2,3-oxathiazoline-4-one-2,2-dioxides.
    Notes: Sulfonylisocyanate RSO2NCO (E = Cl, F, CF3) reagieren mit (CF3)2CN2 bei 100-160°C zu 1,2,3-Oxathiazol-4-on-2-oxidenWährend der Ring IIa mit Methanol gespalten wird (Bildung von FSO2—NH—C(O)— C(CF3)2OH), erhält man bei der Umsetzung mit WasserDas Proton dea Hydrolyseprodukts läßt sich durch Metallatome ersetzen, besonders das Silbersalz eignet sich zur Darstellung weiterer 1,2,3-Oxathiazolin-4-on-2,2-dioxide.
