Synthesis of 3-Substituted Pentane-2,4-Diones: Valuable Intermediates For Liquid Crystals

General procedures for the synthesis of six series of 3-substituted pentane-2,4-diones are described. The diones mere used as intermediates in the preparation of pyrazoles, isoxazoles, and coordination complexes whose mesogenic properties have been studied. Nematic and smectic phases have been obtai...

Summary:General procedures for the synthesis of six series of 3-substituted pentane-2,4-diones are described. The diones mere 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.
