Synthesis and Infrared Absorption Spectra of α-methyl-2′-hydroxy-chalcones: I. α-methyl-2′-hydroxychalcone and its 4-Substituted Derivatives

Six 2′-hydroxychalcone derivatives with a methyl group on the α-position were synthesized. Infrared absorption spectra of these new compounds are discussed taking their corresponding α-hydrogen chalcoes which were also synthesized for comparison. This latter study is also utilized as a proof for the structures of these compounds of a new series.
