The 1,t-2,t and 1,t-2,c-isomers of 1,2-dibenzoyl-3-phenylcyclopropanes have been prepared by the cycloaddition of carbonyl-stabilized sulfur ylides to trans-chalcones under phase-transfer conditions.The configurations of the isomers were characterized by

cis-1,2-Dibenzoyl-3-arylcyclopropanes (II) have been prepared by treating α,β-unsaturated ketones (I) and phenyldimethylsulphonium bromide in methylene chloride with 50percent NaOH solution in the presence of benzyltriethylammonium chloride.The compounds
Studies on Stabilized ?-Sulphuranes: Cyclopropanation with Dimethylphenacylidenesulphurane
Tewari, R. S.,Awasthi, A. K.
, p. 155 - 156 (2007/10/02)
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.
