Synthesis of 3-Substituted Pentane-2,4-diones: Valuable Intermediates for Liquid Crystals

Article abstract of DOI:10.1021/jo00115a023

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 relationship between molecular structure and mesogenic properties has been explored.
