    Notes: Synthesis and Reactions of Bis(fluorosulfinyl)difluoromethane, F2C(SOF)2From F2C(SF3)2 (1) and AsF5 the thermally labile monosulfonium salt F3SCF2SF2+ AsF6- (2) is prepared in SO2 as a solvent, while under the same conditions the corresponding tetrafluoroborate is solvolyzed to give an isomeric mixture of F2C(SOF)2 (5a,b). In the reaction of 5a,b with N-silylated amines F2C[S(O)NMe2]2 (7a,b), (8a,b), and (9a,b) are formed. The structure of the cis derivative 8b has been determined by X-ray diffraction. From 5a,b and HCl the rather unstable F2C[S(O)Cl]2 (10a,b) is obtained, which is hydrolyzed to F2C[S(O)OH]2 (11a,b).

    Notes: Fluoro- and Fluorooxodithietanes (1) was isolated from the reaction of 2,2,4,4-tetrafluoro-1,3-dithietane (3) with CIF in an unpassivated monelcylinder. The hydrolysis of 1 gives (2): the trans derivative (2b) and the cis isomer (2a) are formed in a 4:1 ratio. (7) is oxidized by CIF at room temperature to give the known (8) in 87% yield. At 50°C from 8 and (9) is formed besides the ring cleavage products CF3SO2CF2SF4Cl (10) and CF3SO2CF2SF5 (11). The gasphase structure of 9 (e.d.) is described. (5) and (13) coordinate by the oxygen of the SO group to AsF5, with an unstable sulfonium salt is formed, while from the reaction of AsF5 and SbF5 with 8 (15 a, b, M = As, Sb) are isolated.

    Pentafluorethylschwefeltrifluorid: Synthese und ReaktionenProfessor Anton Meller zum 65. Geburtstag gewidmet (1997)

    Description / Table of Contents: Pentafluorethyl Sulfurtrifluoride: Synthesis and ReactionsBy oxidation of (C2F5S-)2 (1) with AgF2 at 0°C a mixture of C2F5SF3 (2) and C2F5SF5 (3) besides C2F5S(O)F (4) is formed. With elemental fluorine only 3 is isolated, an intermediate in this reaction is (C2F5SF4-)2 (5). At -40 to -30°C the mixture of 2, 3 and 4 was reacted with TASF and AsF5, to give TAS+ C2F5SF4- (6), TAS+ C2F5S(O)F2- (7) and C2F5SF2+AsF6- (8), respectively. While 6 and 7 decompose rapidly in solution even at low temperatures, of thermally stable 8 the solid state structure was determined by x-ray diffraction.
    Notes: Durch Oxidation von (C2F5S-)2 (1) mit AgF2 bei 0°C entsteht ein Gemisch aus C2F5SF3 (2) und C2F5SF5 (3) daneben bildet sich C2F5S(O)F (4); mit elementarem Fluor wird nur 3 isoliert, ein Zwischenprodukt bei dieser Reaktion ist (C2F5SF4-)2 (5). Das Gemisch aus 2, 3 und 4 wurde bei T=-40 bis -30°C mit TASF bzw. AsF5 umgesetzt, mit TASF reagieren 2 und 4, mit AsF5 bildet lediglich 2 ein isolierbares Salz. Während sich TAS+ C2F5SF4- (6) und TAS+ C2F5S(O)F2- (7) bei tiefen Temperaturen in Lösung rasch zersetzen, konnte von dem thermisch stabilen C2F5SF2+AsF6- (8) eine Röntgenstrukturanalyse angefertigt werden.
