Structures and Conformations of ((Trifluoroacetyl)imido)(trifluoromethyl)sulfur Fluoride, CF3C(O)NS(F)CF3

“…CF 3 C(O)NdSFCF 3 was obtained by reaction between CF 3 C(O)NH 2 and CF 3 SF 3 , in the presence of NaF. 20 The product was purified at reduced pressure by several trap-to-trap distillations. CF 3 C(O)NdSFCF 3 reacted with the humidity of the air and had to be handled in a vacuum line and dry bag.…”

Advances in the Chemistry of Sulfimides and Related Compounds

“…135 In the presence of triethylamine, CH-acids are acylated by the chlorides to form N-substituted sulfimides (Scheme 24).…”

2‐Benzothiazolyl‐N‐(arenesulfonyl)‐sulfinimidoyl fluorides

“…Sulfinimidoyl fluorides are practically unexplored compounds that, apparently, are connected with the absence of convenient methods of their preparation. The known syntheses of sulfinimidoyl fluorides are based on the use of remote and toxic reagents: perfluoroalkens [8], thiazyl fluoride [9], fluorine [10][11][12], trifluoromethylsulfur trifluoride [12][13][14] and these methods result only in perfluorosulfinimidoyl fluorides.…”
