2,2-Diarylacetaldehydes (VII) have been obtained by selective and controlled reduction of 2,2-diaryl-1-nitroethylenes (IV) in acid medium, and also by acid hydrolysis of 2,2-diarylvinyl-N-acetamides (VI).Nitroalkenes (IV) have been prepared by the reaction of 2,2-diarylethylenes (I) with nitrous acid whereas N-acetamide derivatives (VI) have been obtained by reductive acetylation of the nitro compounds (IV).A number of 1,1,4,4-tetraarylbuta-1,3-dienes (XI) have been obtained by the condensation of 2,2-diarylacetaldehydes (VII) with appropriate 2,2-diarylethylenes (I).Structures of the products have been assigned on the basis of analytical data and chemical and spectral evidences.
