Synthetic Route of 13362-78-2 , The common heterocyclic compound, 13362-78-2, name is (E)-1,2-Di(pyridin-4-yl)ethene, molecular formula is C12H10N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
General procedure: To a stirred solution of HL (95.6mg, 0.4mmol) in absolute EtOH (10ml), solid Zn(OAc)2·2H2O (43.9mg, 0.2mmol) and absolute bpe (trans-1,2-bis(4-pyridyl)ethylene, 18mg, 0.1mmol) were added separately, and the final mixture was heated under reflux for 5h. A solution of Ln(NO3)3·6H2O (0.2mmol, Ln=Nd, 0.087g; Ln=Yb, 0.089g; Ln=Er, 0.088g; Ln=Gd, 0.090g) in absolute MeCN (20ml) were added sequentially. Then the mixture was refluxed for another 3h. The respective yellow clear solution was then cooled to room temperature and filtered. Diethyl ether was allowed to diffuse slowly into the respective solution at room temperature and pale yellow microcrystallines 5?8 were obtained in about three weeks, respectively.
The synthetic route of 13362-78-2 has been constantly updated, and we look forward to future research findings.
