Synthesis of aromatic amine type dendrimer in the presence of palladium(0) catalyst was written by Moriwaki, Kazuyuki;Takada, Masahiro;Ohno, Toshinobu;Miyata, Toshiyuki. And the article was included in Kagaku to Kogyo (Osaka) in 2001.HPLC of Formula: 162258-89-1 This article mentions the following:
Aromatic amine type dendrimer bis(4′-tert-butylbiphenyl-4-yl)aniline (BBA) and bis[4-bis(4′-tert-butylbiphenyl-4-yl)aminophenyl]aniline (bis-BBA) were successfully synthesized using aryl bromide and aniline. Aryl bromide and aniline easily reacted in the presence of Pd catalyst to give these tertiary aromatic amines. In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1HPLC of Formula: 162258-89-1).
4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.HPLC of Formula: 162258-89-1
