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).
