Abstract
The E,Z-and E,E-bis(styryl)sulfones (V & X) have been synthesized from 4-methylphenylacetylene (I) and 4-methylstyrene (VI), respectively. The cyclopropanation of V and X with dimethylsulfoxonium methylide by PTC or Corey and Chaykovsky methods gave E,E-1,1′-bis(2-arylcyclopropyl)sulfones (XI) only. The spectral parameters of these compounds have been discussed.
