Reaction of bis(collidine)iodine(I) (or bromine (I)) hexafluorophosphate with acetylenic acids led to the corresponding iodo(or bromo)acetylenes in high yields. This halodecarboxylation reaction was also observed with acrylic acids substituted in position 3 by an aryl group or an heteroatom.
NUCLEOPHILIC REACTIONS AT A VINYLIC CENTER. XX. BASE-CATALYZED REARRANGEMENT OF ARYL β,β-DIBROMOVINYL SULFONES TO Z-ARYL α,β-DIBROMOVINYL SULFONES

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.
