Liquid crystals were discovered in 1888 but have been studied seriously during the past 20 years. The kinds of molecules that form liquid crystals on heating and by mixing two or more substances are explained. Properties of liquid crystals and relate

In the couse of our investigations of liquid crystals as solvents, we wish to report some kinetic data for the Claisen rearrangement. The thermal rearrangement of allyl phenyl ethers (1) proceeds by an intramolecular path to give an ortho-dienone (II

The kinetics and mechanism of the Claisen rearrangement of a series of para-substituted allyl phenyl ethers are determined in nematic and isotropic solvents. The influences of the solvent systems are compared. The rearrangement reactions are first-or
