A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article£¬once mentioned of 15746-57-3, HPLC of Formula: C20H16Cl2N4Ru
[Ru(bpy)2(bqdiBr2)](PF6)2 bearing a 3,6-dibromo-1,2-benzoquinone diimine ligand (bqdiBr2 = Br-C6H2(NH)2-Br): Synthesis and its cross coupling reactions with organostannanes and organoboronic acids
[Ru(bpy)2(bqdiBr2)](PF6)2 ([1](PF6)2, bpy = 2,2?-bipyridyl, bqdiBr2 = 3,6-dibromo-1,2-benzoquinone diimine) was synthesized by the reaction of 3,6-dibromo-1,2-phenylenediamine with [RuCl2(bpy)2] in air, and the reactivity of [1](PF6)2 in Pd-catalyzed cross-coupling reactions with metalated thiophene and benzene was investigated. The structure of [1](PF6)2 was determined using X-ray crystallography. The Migita-Kosugi-Stille cross-coupling of [1](PF 6)2 with 2 equiv of Th-SnBu3 (Th = 2-thienyl; Bu = butyl) afforded a 3,6-di(2-thienyl)-1,2-benzoquinone diimine (Th-C 6H2(NH)2-Th)-coordinated Ru(II) complex [2](PF6)2. Similarly, the Suzuki-Miyaura cross-coupling of [1](PF6)2 with 2 equiv of CH3OC 6H4-B(OH)2-p proceeded smoothly to afford a p-CH3OC6H4-C6H2(NH) 2-C6H4OCH3-p-coodinated Ru(II) complex, [3](PF6)2. The optical and electrochemical properties of these complexes were evaluated based on the presence of the extended pi-conjugated diimine ligand in the diimine moiety. The Stille cross-coupling of [1](PF6)2 with 1 equiv of Me 3Sn-C4H2S-SnMe3 (C4H 2S: thiophene-2,5-diyl) afforded a pi-conjugated polymer consisting of the [Ru(bpy)2(bqdi)]2+ units.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.HPLC of Formula: C20H16Cl2N4Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
