The structures of the products were established and studied by X-ray diffraction, NMR spectroscopy, and electronic spectroscopy. All products had the <i>E</i>,<i>E</i>-geometry. The oxidation and reduction potentials of the dienones were determined by cyclic voltammetry. The potentials were shown to depend on the nature, position, and number of substituents in the benzene rings. A linear correlation was found between the difference of the electrochemical oxidation and reduction potentials and the energy of the long-wavelength absorption maximum. This correlation can be employed to analyze the propertiesACS omegaStructure-Property Relationships of Dibenzylidenecyclohexanones.PMC897310219-13-00020Nuriev VNFomina MVFreidzon AYVatsadze SZStarostin ROGromov SPMoiseeva AAKuz'mina LGfalseStructure-Property Relationships of Dibenzylidenecyclohexanones.A series of symmetrical dibenzylidene derivatives of cyclohexanone were synthesized with the goal of studying the physicochemical properties of cross-conjugated dienones (ketocyanine dyes).
