Poly‐1,3,4‐oxadiazoles. III. Alicyclic poly‐1,3,4‐oxadiazoles
Die Makromolekulare Chemie, 1966AbstractSome alicyclic poly‐1,3,4‐oxadiazoles were prepared from cycloalkanedicarboxylic dihydrazides or from cycloalkanedicarboxylic acids and hydrazine sulfate by solution polycondensation in polyphosphoric acid. These polymers were characterized by high melting temperature.

Abstract The infrared absorption spectrum of 1,3,4-oxadiazole has been recorded in the region 5000-400 cm −1 in the vapor and in the liquid phases, in CS 2 and C 2 Cl 4 solutions. Also, the infrared absorption spectrum of liquid 2,5-dimethyl-1,3,4-oxadiazole was recorded in the same region. A tentative assignment of the fundamental vibrations of 1,

Poly‐1, 3,4‐oxadiazoles. II. Aliphatic poly‐1,3,4‐oxadiazoles
Die Makromolekulare Chemie, 1966AbstractAliphatic poly‐1,3,4‐oxadiazoles were prepared from aliphatic dicarboxylic dihydrazides or from dicarboxylic derivatives and hydrazine sulfate by solution polycondensation in polyphosphoric acid. Their preparation and physical properties, such as solubility, crystallinity, and thermal stability are described.

Mass spectrometric analysis of 1,2,4‐Oxadiazoles and 4,5‐Dihydro‐1,2,4‐Oxadiazoles
Mass Spectrometry Reviews, 2004Abstract1,2,4‐Oxadiazoles and 4,5‐dihydro‐1,2,4‐oxadiazoles are an interesting class of compounds because of their pharmacological and other properties. Although short descriptions of these compounds under mass spectrometric conditions exist, we thought it worthwhile to write a comprehensive review of this class of compounds.
