At room temperature in the presence of CsF sulfur-oxide-chloride-fluoride-imides RfNSOFCl (8) (Rf = CF3, C2F5, i-C3F7, C6F5) are formed from N-perfluoroalkyl-sulfinyl-imides and Cl2.At prolonged reaction times or higher temperatures the chloride is exchanged and the difluorides RfNSOF2 are isolated in high yields.In the same way (CF3)2CFNS(O)ClCF3 (12) and (CF3)2CClNS(O)ClCF3 (13) are obtained from (CF3)2C=N-S(O)CF3 (9) and Cl2/CsF. 12 can be fluorinated by CsF to give (CF3)2CFNS(O)FCF3 (14). 14 is also observed, when fluorine is added to 9 via XeF2 in the presence of BF3, but mainly C-S bond cleavage occurs.SF5NS(O)FCF(CF3)2 (19) was identified by spectroscopic methods from the reaction of SF5NSOF2 and CF3CF=CF2 in the presence of CsF. - Keywords: Sulfinyl-imides, Sulfur-oxide-chloride-fluoride-imides

Substitution of the hexafluoroisopropylidenimino group for chlorine or fluorine occurs readily when the lithium salt of (CF3)2C=NH is reacted with inorganic compounds of groups IIIa-VIa. The formation of lithium halide prevents nucle
