Perfluoro-1,3,4-oxadiazoles

Journal of Fluorine Chemistry, 1992
Abstract Some new polyfluorinated 1,3,4-oxadiazoles have been obtained via a two-step method. The cycloadditions of the 1,3,4-oxadiazoles have been studied and an analysis of the energies of the frontier orbitals calculated by the MNDO method indicates a LUMO-dependent pathway for cycloaddition.

Banana-Shaped 1,2,4-Oxadiazole Analogues of 1,3,4-Oxadiazoles

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2001
Abstract In the last years bent banana-shaped mesomorphic molecules found an increasingly great interest among theoreticians and experimentalists due to the nature of this type of liquid crystals to exhibit a spontaneous polarization in the absence of any chiral group in the molecules.
