1,2-Diarylethanols were obtained in high yields by ultrasonic irradiation of mixtures of lithium sand, benzylic chlorides, and arenecarbaldehydes or aryl methyl ketones.The mass spectra of the alcohols contained dominant peaks for species formed by dehydration, α-cleavage processes and rearrangement involving hydrogen transfer.Acid-catalyzed dehydration of the alcohols gave the corresponding stilbenes in quantitative yields.
