Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 15862-18-7, molcular formula is C10H6Br2N2, introducing its new discovery. Formula: C10H6Br2N2
A linear bis-porphyrin bridged by a 5,5?-diphenyl-2,2?-bipyridine rod-like spacer complexing a [Ru(phen)2]2+ fragment has been synthesized in 7.4% yield by one-pot condensation of 3,5-di-tert-butylbenzaldehyde, 4,4?-dimethyl-3,3?-dihexyl-2,2?-methylenedipyrrole and the [Ru(phen)2]2+ complex of 5,5?-bis(p-formylphenyl)-2,2?-bipyridine, followed by chloranil oxidation. The protected dialdehyde (5,5?-bis[(5,5-dimethyl-1,3-dioxan-2-yl)phenyl]-2,2?-bipyridine) was obtained in 80% yield by Suzuki coupling of 2-[4-(5,5-dimethyl-1,3-dioxan-2-yl)phenyl]-4,4,5,5-tetramethyl-1, 3-dioxaborolane and 5,5?-dibromo-2,2?-bipyridine, using [Pd(PPh3)4] as catalyst. A new procedure is reported for the preparation of 5,5?-dibromo-2,2?-bipyridine, which is obtained in 80% yield by Stille homocoupling of 2,5-dibromopyridine in the presence of hexamethylditin.
