Substituted 1

Cyclopropanation of substituted phenyl styryl sulfones 1 with dimethylsulfonium phenacylides was carried out by two different methods (under PTC catalysis with in situ generation of the ylides and by direct addition of ylides) to obtain a series of substituted 1-benzenesulfonyl-2-benzoyl-3-phenylcyclopropanes 2. The PTC method was found to be more facile and efficient. The spectral data of cyclopropanes 2 are discussed.
