, p. 27 - 32 (2007/10/03)
The preparation of the title compounds (Z)- and (E)-1, which are synthetic substitutes for the unstable bis(phenylsulfonyl) acetylene and key reagents for the asymmetric preparation of polycyclic ketones, has been revisited and improved. Starting from inexpensive materials such as trichloroethylene, thiophenol, and hydrogen peroxide, (Z)- and (E)-1 are selectively obtained in multigram quantity in 52% overall yields.

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,
