Oxidation for unsymmetrical bromo-1,10-phenanthrolines and subsequent hydroxylation, decarbonylation and chlorination reactions was written by Peng, Yu-Xin;Hu, Bin;Huang, Wei. And the article was included in Tetrahedron in 2018.Synthetic Route of C12H7BrN2 This article mentions the following:
Systematic investigation on the oxidation of unsym. bromo-phens is presented, where the reaction temperature is found to be the key parameter to generate oxidation or oxidation-bromination products. The regioselective C3-brominated compounds are produced in moderate yields in the cases of 2-bromo-phen and 4-bromo-phen. Subsequent hydroxylation and decarbonylation for bromo-phds are also studied, where a series of bromo-diazafluorenones and phen-triones have been isolated. Furthermore, various chlorination products have been obtained by treating bromo-phds or bromo-phts with excess POCl3. In the experiment, the researchers used many compounds, for example, 2-Bromo-1,10-phenanthroline (cas: 22426-14-8Synthetic Route of C12H7BrN2).
2-Bromo-1,10-phenanthroline (cas: 22426-14-8) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Synthetic Route of C12H7BrN2
