The rapid preparation of sym. azines and N,N’-Diacylhydrazines by NH2NH2.H2O in presence of mol. iodine or bromine at 0-10°C is described. This method afforded an exceedingly convenient route to 1,3,4-Oxadiazoles. The reactions are safe, affording excellent yields of high purity products in shorter durations and the workup procedure involves no solvent extraction, which is environmentally acceptable. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Recommanded Product: 15420-02-7).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Recommanded Product: 15420-02-7
