3-Bromoimidazo[1,2-b]pyridazine-bromine and 3-bromo-6-chloroimidazo[1,2-b]pyridazine-bromine complexes: new brominating agents for organic compounds was written by Stanovnik, Branko;Tisler, Miha;Drnovsek, Iztok. And the article was included in Synthesis in 1981.Electric Literature of C6H3BrClN3 This article mentions the following:
Title compounds I.HBr.Br2 (R = H or Cl) were prepared and used to brominate a variety of alkenes, ketones, 3-oxoalkanoic esters, and monocyclic and polycyclic N-heterocyclic compounds at room temperature or on gentle heating, monobrominated compounds are obtained in practically quant. yields. In the experiment, the researchers used many compounds, for example, 3-Bromo-6-chloroimidazo[1,2-b]pyridazine (cas: 13526-66-4Electric Literature of C6H3BrClN3).
3-Bromo-6-chloroimidazo[1,2-b]pyridazine (cas: 13526-66-4) belongs to pyridazine derivatives. The pyridazine structure is a popular pharmacophore which is found within a number of herbicides such as credazine, pyridafol and pyridate. Pyridazine compounds have attracted interest in various fields like medicinal, industrial, and agricultural research as they are used for numerous biological activities and other applications.Electric Literature of C6H3BrClN3
