With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1662-01-7,4,7-Diphenyl-1,10-phenanthroline,as a common compound, the synthetic route is as follows.
General procedure: The preparation of the homologous series of osmium complexes with alpha diimineligands was modified from previous literature methods [5]. The precursor Os(L)2Cl2 was synthesized by refluxing ammonium hexachloroosmate in a 1:2 M ratio with L = 2,2?-bipyridine (bpy), 1,10-phenanthroline (phen), or bathophenanthroline (dpp) in 10 mL of ethylene glycol under nitrogen for 45 min. After cooling to room temperature, sodiumhydrosulfite (0.17 M) was added to reduce the osmium from Os(IV) to Os(II). Precipitation of Os(bpy)2Cl2,Os(phen)2Cl2, and Os(dpp)2Cl2 was achieved via an ice-bath,and the solid was washed with deionized water and ethylether. Yields were close to 80 %.
1662-01-7, The synthetic route of 1662-01-7 has been constantly updated, and we look forward to future research findings.
