In 1970,Zhurnal Prikladnoi Khimii (Sankt-Peterburg, Russian Federation) included an article by Sharnin, G. P.; Moisak, I. E.; Gryazin, E. E.. Quality Control of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl. The article was titled 《Synthesis of 1,3,5,-triphenylbenzene derivatives with fixed position of the functional groups》. The information in the text is summarized as follows:
PhCOMe and 9 acetophenones containing electron-withdrawing substituents in the meta and para positions are self-condensed, by using a K2S2O7-H2SO4 mixture, to the corresponding 1,3,5-triphenylbenzene derivatives in 21-75% yield after 6-10 hr at 80-180°. However, 3-HO-, 3-NH2-, 2-NO2-, and 2-ClC6H4COMe resinify under these conditions. The experimental process involved the reaction of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8Quality Control of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl)
3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. The most pervasive is the naturally produced bromomethane.Quality Control of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl
