Efficient preparation of E-β-iodovinyl phenylsulfone by finkelstein reaction at a vinylic center

Treatment of E-β-chlorovinyl phenylsulfone, a crystalline compound that can be conveniently prepared on a large scale from 1,1,2-trichloroethane, by sodium iodide in acetone at ca 130 °C, in a sealed vessel, affords the title iodosulfone in good yield.

Reactions of (E)-2-Iodo-1-tosyl-1-alkenes as Useful Synthetic Intermediates

(E)-2-Iodo-1-tosyl-1-alkenes readily available by iodosulfonization of 1-alkynes were found to be useful synthons for the regio- and/or stereoselective preparation of 1-tosyl-1-alkynes, 1-tosyl-2-alkynes, (Z)-vinyl and (Z)-allyl sulfones, β-tosyl enamines
