Synthetic Route of C24H12Br6On September 30, 1996 ,《Multinucleating ligands from multiple palladium(0)-catalyzed cross-coupling reactions – synthesis and characterization of a trinuclear cyclometalated ruthenium(II) complex and a hexanuclear EPR-active molybdenum complex》 was published in Inorganica Chimica Acta. The article was written by Cargill Thompson, Alexander M. W.; McCleverty, Jon A.; Ward, Michael D.. The article contains the following contents:
Two multinucleating ligands were prepared from 1,3,5-tris(3,5-dibromophenyl)benzene by multiple Pd(0)-catalyzed cross-coupling reactions. 1,3,5-Tris[3,5-bis(4-pyridylethenyl)phenyl]benzene (L1) has six remote pyridyl moieties, each of which can coordinate a 17 valence-electron {Mo(tp*)(NO)Cl} fragment (tp* = hydrotris(3,5-dimethylpyrazolyl)borate), affording hexanuclear [{Cl(NO)(tp*)Mo}6(L1)] (1). 1,3,5-Tris[3,5-bis(2-pyridyl)phenyl]benzene (L2) incorporates three potentially terdentate, cyclometalating N,C,N-donor sets, and can coordinate three {Ru(tpy)}2+ fragments (tpy = 2,2′:6′,2”-terpyridine) giving trinuclear [{(tpy)Ru}3(L2)][PF6]3 (2). Complex 1 is EPR active, with nearest-neighbor pairs of Mo centers displaying magnetic exchange interactions. Electrochem. studies of the two complexes suggest that there is little ground-state interaction between the metal centers in either case.3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8Synthetic Route 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. Synthetic Route of C24H12Br6 In contrast, terrestrial plants account only for a few bromine-containing compounds.
