✦ Synopsis

Halogenation of the potassium or silver salts of bis((trifluoromethyl)sulfonyl)methane (CF 3 SO 2 ) 2 CH 2 and its cyclo analogues (CF 2 ) n SO 2 -CH 2 SO 2 CF 2 with N-fluoro-bis((trifluoromethyl)sulfonyl)imine (CF 3 SO 2 ) 2 NF, chlorine or bromine gave good yields of the corresponding ␣-halo disulfones (CF 3 SO 2 ) 2 CHX and (CF 2 ) n SO 2 CHXSO 2 CF 2 (X: F, Cl, Br; n ‫ס‬ 1,2). Some chemical transformations of these fluorinated ␣-halo-disulfones are described. ᭧ 1999

Domino reactions facilitate the rapid assembly of complex products in a one-pot process.
