IODOFLUOROALKYLSULFONYL FLUORIDES - SYNTHESIS AND CONVERSION TO NEW DERIVATIVES

Article abstract of DOI:10.1016/S0022-1139(00)82721-9

The thermal reaction of I(CF2)2O(CF2)2SO2F 1 with unsaturated alkenes and alkynes, in the presence of benzoyl peroxide, was studied as a means for preparing reactive iodofluoroalkylsulfonyl fluorides.The following compounds have been prepared and characterized: R(CF2)2O(CF2)2SO2F where R = I(CH2)2, I(CH2)4, CH3CH2, -(CH2)3-, ClCH2CHICH2, ICH=CH (cis and trans), CF3CH=CH (E and Z).The alcohol, HO(CH2)2(CF2)2O(CF2)2SO2F, and olefin, H2C=CH(CF2)2O(CF2)2SO2F, have been also synthesized from the corresponding iodoalkane.Infrared, mass and NMR spectra data are presented in order to support assigned structures.
