A controlled and selective bromination of phenols by benzyltriphenylphosphonium tribromide was written by Hajipour, Abdol Reza;Mallakpour, Shadpour E.;Imanieh, Hassein;Pourmousavi, Seied Ali. And the article was included in Journal of Chemical Research, Synopses in 2002.Category: bromides-buliding-blocks This article mentions the following:
Reactions of phenols with benzyltriphenylphosphonium tribromide in dichloromethane-MeOH mixture (2:1) gave mono, di and tri brominated phenols at room temperature with high selectivity and good yields. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-chloro-6-nitrophenol (cas: 58349-01-2Category: bromides-buliding-blocks).
4-Bromo-2-chloro-6-nitrophenol (cas: 58349-01-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). 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.Category: bromides-buliding-blocks
