Synthesis of phthalonitriles using a palladium catalyst was written by Iqbal, Zafar;Lyubimtsev, Alexey;Hanack, Michael. And the article was included in Synlett in 2008.Formula: C6H5Br2N This article mentions the following:
An easy synthetic method to obtain phthalonitriles from o-dibromobenzenes under mild conditions in high yields using Zn(CN)2 and a catalytic amount of tris(dibenzylideneacetone)dipalladium and 1,1′-bis(diphenylphosphino)ferrocene is described. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Formula: C6H5Br2N).
3,4-Dibromoaniline (cas: 615-55-4) 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). In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Formula: C6H5Br2N
