D. Viets et al., FORMATION AND STRUCTURE OF S(O)CF2S(O)O, THE MOST SIMPLE PERFLUOROALKANE BIS(SULFINIC ACID)ANHYDRIDE, Journal of fluorine chemistry, 89(1), 1998, pp. 55-57
Difluoromethane bis(sulfinic acid)F2C(S(O)OH)(2) (3) was isolated from
the hydrolysis of F2C(S(O)F)(2) (1) by moist air. Single crystals of
the corresponding anhydride S(O)CF2S(O)O (2) were obtained after Cs+[F
2C(SF3)(2)F](-) (4) was stored in a glass vessel for several weeks. Th
e crystal structure of 2 and preliminary results for 3 are reported. (
