1- or 2-p-Tolylsulfonyl(=tosyl)-1-alkenes, vinylic sulfones, were regioselectively prepared from 1-alkenes via iodosulfonization or sulfonylmercuration and also from 1-haloalkanes by the homologation or unhomologation methods.The vinylic sulfones thus prepared were further converted to the corresponding allylic sulfones under basic conditions.The stereochemistry of this conversion was discussed.One-carbon homologated allylic sulfones were directly obtained from aldehydes in good yields by the reaction with diethyl phenylsulfonylmethylphosphonate and 1,8-diazabicycloundec-7-ene (DBU) under mild conditions.

2-Pyrrolidinoalkyl p-tolyl sulfones, which were readily available by the addition of pyrrolidine to vinylic or allylic sulfones, were converted to the corresponding α-alkylated vinylic sulfones through α-alkylation followed by elimination of pyrrolidino g

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
