Cheng, Ge; Zhao, Ling; Wang, Yuechuan published an article in Gaofenzi Xuebao. The title of the article was 《Synthesis and characterization of polyphenylene dendrimers containing terminal trimethylsilyl groups》.Electric Literature of C24H12Br6 The author mentioned the following in the article:
Polyphenylene dendrimers containing terminal trimethylsilyl groups have been synthesized by a phosphine-free palladium chloride-catalyzed Suzuki coupling of 1,3,5-tris(3′,5′-dibromophenyl)benzene with aryl boronic acids. These macromols. were characterized by Fourier transform IR (FTIR), NMR and matrix assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectra. Gel permeation chromatog. (GPC) indicated that the hydrodynamic radius of I, with trimethylsilyl (TMS) groups substituted at para-positions on its terminal benzene rings, was larger than that of its Me derivative, with trimethylsilyl groups substituted at meta-positions on its terminal benzene rings. X-ray powder diffraction patterns showed that dendrimer I was of a certain amount of crystallinity and the Me derivative dendrimer was amorphous.3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8Electric Literature of C24H12Br6) was used in this study.
3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Electric Literature of C24H12Br6 Moreover, several studies demonstrate that the average proportion of bromine in drugs is significantly higher than that in natural products.
