It was found that the desulfonylation reaction of α,α-dialkylated (E)-allylic sulfones with a base preferentially affords the sterically unfavorable (Z)-alkadienes. The relative degree of the "syn-effect", which is herein defined as an effect which stabil

(E)- and (Z)-vinilyc sulfones were prepared regio- and stereoselectively from 1-alkenes or 1-alkynes in high yields via iodosulfonization in AcOEt-H2O.The vinylic sulfones thus prepared were converted to the corresponding allylic sulfones by treatment wit

1 or 2-p-Toluenesulfonyl(=tosyl)-1-alkenes were regioselectively prepared from 1-alkenes via iodosulfonization or sulfonylmercuration, respectively.Conversion of 1-tosyl-1-alkenes to the corresponding allylic sulfones, 1-tosyl-2-alkenes, was achieved by t

A convenient synthesis for various β-iodo sulfones has been developed.The reaction involves additions of alkane- and arenesulfonyl iodides to simple and cyclic alkenes under the catalytic action of copper(II) chloride.The favored stereochemical results for cyclic alkenes have been rationalized in terms of stepwise addition of both portions of the addend from the diaxial direction.
