| Abstract: | On the Reaction of Perfluoro Isobutene with Thiazylfluoride and Thiazyltrifluoride From thiazylfluoride (1) and perfluoro-isobutene (2) (CF3)3C? N?S?N? S? C(CF3)3 (4) isr formed in the presence of CsF. With NSF3NSF2C(CF3)3 (8) is obtained, which isomerizes above 100°C to (CF3)3CNSF2 (9). In contrast to 9, with fluoro Lewis-acids 8 forms 1:1 adducts (CF3)3CSF2N · MF5 (M = As, Sb (10a), (10b)). In 50% aqueous KOH 9 hydrolyses to give the amine (CF3)3CNH2. |
