Abstract: | Halogenation of the potassium or silver salts of bis((trifluoromethyl)sulfonyl)methane(CF3SO2)2CH2 and its cyclo analogues (CF2)nSO2‐CH2SO2CF2 with N‐fluoro‐bis((trifluoromethyl)sul‐fonyl)imine (CF3SO2)2NF, chlorine or bromine gave good yields of the corresponding α‐halo disulfones (CF3SO2)2CHX and (CF2)nSO2CHXSO2CF2 (X: F, Cl, Br; n = 1,2). Some chemical transformations of these fluorinated α‐halo‐disulfones are described. © 1999 John Wiley & Sons, Inc. Heteroatom Chem 10: 147–151, 1999 |
