3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Application In Synthesis of 3,4-Dibromoaniline

Bifunctional Indenyl-Derived Receptors for Fluoride Chelation and Detection was written by Tirfoin, Remi;Abdalla, Joseph A. B.;Aldridge, Simon. And the article was included in Chemistry – A European Journal in 2015.Application In Synthesis of 3,4-Dibromoaniline This article mentions the following:

Anion receptors based on a [CpFe(indenyl)] scaffold offer the possibility for the incorporation of adjacent Lewis acidic functions onto a six-membered carbocyclic framework, while at the same time retaining the colorimetric/electrochem. reporter mechanisms available to synthetically simpler ferrocene systems. Thus, [CpFe(indenyl)] systems featuring mutually ortho BMes2 and PPh2Me+ substituents (with either 4,5 or 5,6 regiochem.) are accessible which are capable of cooperative fluoride ion fixation. Simultaneous binding at the borane and phosphonium centers can be established by spectroscopic, structural and computational approaches, and is responsible for the favorable thermodn. associated with F– uptake. Thus, in contrast to simple BMes2 systems, the binding of fluoride is found to be more favorable than the uptake of cyanide (which interacts only with the borane Lewis acid). Moreover, in the case of a 4-(MePh2P)-5-(Mes2B)-7-Me-indenyl derivative, fluoride chelation is signalled not only by a large cathodic shift in the FeII/FeIII potential (>500 mV in THF), but also by a distinct color change from green (for the free receptor) to maroon for the adduct. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Application In Synthesis of 3,4-Dibromoaniline).
