A highly stereoselective synthesis of stilbenes ( trans-1,2-diarylethylenes) was achieved under solvent-free conditions from aryl-aldehydes and aromatic substances bearing an activated methyl group in the presence of anhydrous K2CO3 and poly(ethylene glycol). This method avoided the need for completely anhydrous condition and use of a noxious organic solvent.
