Studies on Carbonyl Stabilized Sulphonium Ylids : Reaction with α,β-Unsaturated Carbonyl Compounds

1,2,3-Trisubstituted-cyclopropanes (3a-j) have been prepared by the reaction of the sulphur ylids phenacylidenedimethylsulphurane (1a) and 4-methylphenacylidenedimethylsulphurane (1b) with α,β-unsaturated ketones (2).The carbonyl stabilized ?-sulphuranes (1) have been generated from their corresponding salts.Structural assignments of the products are based on their IR and PMR data.

Studies on Stabilized ?-Sulphuranes: Cyclopropanation with Dimethylphenacylidenesulphurane

Dimethylphenacylidenesulphurane (2), a stabilized ?-sulphurane has been prepared and reacted with a variety of substituted α,β-unsaturated ketones to afford 1,2,3-triaryl substituted cyclopropanes in fair to good yields.The structural assignments are based on spectral analysis.
