Résumé
General procedures for the synthesis of six series of 3-substituted pentane-2,4-diones are described. The diones were used as intermediates in the preparation of pyrazoles, isoxazoles, and coordination complexes whose mesogenic properties have been studied. Nematic and smectic phases have been obtained in a number of cases, and the relationship between molecular structure and mesogenic properties has been explored. © 1995 American Chemical Society.
