Abstract

Some new bis[1-(2-aroyl-3-aryl)cyclopropylcarbonyl]benzenes and pyridines IV - VI have been prepared by the cycloaddition of dimethylsulfonium phenacylide to 1,1'-(1,3-, 1,4-phenylene, and 2,6-pyridylene)-bis(3-aryl-2-propen-1-ones) I - III by adopting two different methods. The advantages of the PTC method over the other have been discussed. The structures of the compound have been confirmed by spectral data.
