A series of aryl β,β-dibromovinyl sulfones XC6H4SO2CH=CBr2 were synthesized, and their rearrangement to Z-aryl α,β-dibromovinyl sulfones XC6H4SO2CBr=CHBr by the action of KF.18-crown-6 in benzene was studied.The rearrangement rate increases with increase in the concentration of the base -> and with increase in the electron-withdrawing character of the substituent X and does not depend on the temperature.

The reactions of a series of β,β-dihalogenovinyl sulfones with potassium fluoride in benzene in the presence of 18-crown-6 ether were investigated.It was found that they undergo isomerization under the indicated conditions to α,β-dihalogenovinyl sulfones,
