| Abstract: | Preparation of Trifluormethylhalogen Iodate(I) Salts (CH3)4N+CF3IX? (X = F, Cl, Br) and Trifluormethyltrifluormethoxy Iodate(I) (CH3)4N+CF3IOCF3? We describe the preparation of new trifluormethyliodate(I) salts CF3IX? (X = F, Cl, Br, OCF3). (CH3)4N+CF3ICl? and (CH3)4N+CF3IBr? are obtained via addition of CF3I with the corresponded tetramethylammonium halogenide. (CH3)4N+CF3IOCF3? is synthesized by comproportionation of (CH3)4N+CF3ICl? with CF3OCl under formation of Cl2 at ?78°C. (CH3)4N+CF3IF? is formed either, through thermolysis of (CH3)4N+ CF3IOCF3? under separation of COF2, or reaction of CF3I with (CH3)4N+ OCF3?. The thermolabile compounds have been characterized by i.r., Raman, 19F-, 13C NMR spectroscopy. |
