The synthesis of the first trifluoromethanesulfonate esters of the type CF3SO3(CH2)nO3SCF3(n=1,2,3) are reported.The new compounds are prepared from Cl(CH2)nCl by substitutive electrophilic dehalogenation reactions with CF3SO2OX (x=Cl,Br).The extension of this reaction to HCCl3 results in HC(O3SCF3)3 but the compound is unstable at 22 deg.
