Development of new multicomponent reactions for 1,3,4-oxadiazole synthesis
, 2022 Chapter 1 introduces the chemistry of 1,3,4-oxadiazoles with a specific focus on currently available strategies, and methodologies for their synthesis. Five distinct synthetic approaches – 1) dehydration of 1,2-diacylhydrazines; 2) oxidative cyclizations

Advanced Functional Materials, Volume 36, Issue 28, 7 April 2026.Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Synthesis of 2-Isobutyl, 2-Isobutyl-5-aryl and 2-Isobutyl-5-thiol-1,3,4-Oxadiazoles [PDF]
مجلة التربية والعلم, 2007 In this paper the synthesis of some substituted 1,3,4-oxadiazoles from isobutyric acid was studied. The isobutyric acid was converted into the corresponding ethyl ester, which then treated with hydrazine hydrate in ethanol to give the acid hydrazide. The

5-Phenyl-1,3,4-oxadiazol-2-amine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the title complex, C(8)H(7)N(3)O, the C-O [1.369 (2) and 1.364 (3) Å] and C=N [1.285 (3) and 1.289 (3) Å] bond lengths in the oxadiazole ring are each almost identical within systematic errors, although different substituents are attached to the ring. The phenyl ring is inclined to the planar oxadiazole ring [r.m.s. deviation 0.002 Å] by 13.42 (18)°.

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis
ChemPhotoChem, Volume 10, Issue 4, April 2026.This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.
