Some new trans-aryl cyclopropyl sulfones (II) have been prepared by the cycloaddition of dimethylsulfoxonium methylide to trans-styryl aryl sulfones (I) by two different methods. It is observed that the reaction in presence of a phase transfer catalyst proceeds in a facile manner.

The cycloaddition of arylthiocarbenes to styrene gave stereospecifically cis-1-(arylthio)-2-phenylcyclopropanes, which were subsequently oxidized to the corresponding sulfones.The cyclopropanation of α,β-unsaturated sulfones with dimethylsulfonium methylide yielded stereoselectively trans-1-(arylsulfonyl)-2-arylcyclopropanes.The configurational assignments of these compounds have been arrived at on the basis of IR and PMR spectral data.Chemical shifts for ring protons and other substituents reveal that all the substituents tend to cause protons cis to them to appear at higher fields than those trans to them.This has been used as a criterion to distinguish between cis and trans aryl cyclopropyl sulfones.

α,β-Unsaturated sulphones have been cyclopropanated with dimethylsulphonium methylide to obtain stereoselectively trans-1-(arylsulphonyl)-2-arylcyclopropanes (Ia-j).The trans-structure for these compounds has been arrived at on the basis of IR and PMR spe
