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.

The reaction of potassium fluoride with E-β-bromovinyl aryl sulfones in the presence of 18-crown-6-ether leads to a mixture of the sulfones XC6H4SO2CH2CHF2 and E-XC6H4SO2CH=CHF, the ratio of which decreases in the order X=CH3, H, Cl, NO2.The kinetics of n

The radical reaction of tribromoethylene with thiophenol was investigated.In addition to the main product, β,β-dibromovinyl phenyl sulfide, 15-30percent (depending on the conditions) of a mixture of isomeric β-bromovinyl phenyl sulfides is formed. β,β-Dibromovinyl phenyl sulfone was obtained by the oxidation of dibromovinyl phenyl sulfide, and it readily enters into nucleophilic vinyl substitution of both bromine atoms.During comparison of its reactivity with the reactivity of the previously investigated dichlorovinyl phenyl sulfone a clearly defined "element-effect" was detected, indicating cleavage of the C-Hlg bond at the rate-determining stage.
