Abstract: In this paper the synthesis of 4'-substituted 3-isothiocyanato- and 4-isothiocyanatochalcones via nitro- and aminochalcones is described. The infrared,, ultraviolet, and NMR spectra of above compounds are studied. It follows from the study of infrared spectra that the rotational isomers exist only in the presence of electron-acceptor substituents in the 4/-position
