A unique approach to the synthesis of 2,3,4,5-substituted polybrominated biphenyls: quantitation in FireMaster FF-1 and FireMaster BP-6 was written by Kubiczak, Gerhard A.;Oesch, Franz;Borlakoglu, Juergen T.;Kunz, Horst;Robertson, Larry W.. And the article was included in Journal of Agricultural and Food Chemistry in 1989.Application of 615-55-4 This article mentions the following:
A scheme is presented that allows the efficient synthesis of four anilines (3,5-di-, 3,4,5-tri-, 2,3,4,5-tetra-, and 2,3,4,5,6-pentabromoanilines) as well as 1,2,3,4-tetrabromobenzene (I) from a single starting material. All of these products are useful precursors in the synthesis of polybrominated biphenyls (PBBs). The aryl-aryl coupling of bromoanilines with I provides a versatile approach to the synthesis of 2,3,4,5-tetrasubstituted PBBs for the first time. The synthesis and characterization of nine such PBBs are reported here. 2,2′,3,3′,4,4′,5,5′-Octabromobiphenyl was a byproduct of each coupling reaction, ranging from <2% to 63% of the polybrominated biphenyl products. Capillary gas chromatog. quantitation of the nine synthetic PBBs in FireMaster FF-1 and FireMaster BP-6 is presented. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Application of 615-55-4).
3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. 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.Application of 615-55-4
