Synthesis and reactivity of ruthenium tridentate bis-phosphinite ligand complexes.
The tridentate ligands E(CH2CH2OPiPr2)2 (E = NH 1, E = S 2) were employed in the synthesis of a number of ruthenium complexes. Reaction of these ligands with (Ph3P)3RuCl2 afforded the dimers [Ru(HN(CH2CH2OPiPr2)2)Cl(μ-Cl)]2 (3) and [(Ru(E(CH2CH2OPiPr2)2))2(μ-Cl)3][X] (E = NH, X = PF64, E = S, X = Cl 5), respectively. Using (Ph3P)3RuHCl in reactions with 1 gave Ru(NH(CH2CH2OPiPr2)2)(PPh3)HCl (6)...
متن کاملNew Applications of Tridentate Bis(oxazoline) Ligands in Asymmetric Catalysis
Finding interactions between microRNAs and their mRNA targets is a challenging experimental and computational problem. While several novel experimental high throughput approaches have been developed for measuring miRNA expression, the amount of data generated from these technologies is dwarfed by the amount of data existing in current gene expression microarray repositories. Many microRNAs over...
متن کامل3,3′′-Bis(saccharin-6-ylmethyl)-1,1′:3′,1′′-terphenyl – Precursor of A New Tetradendate Bis-bridging Ligand
Dedicated to Professor Heribert Offermanns on the occasion of his 75th birthday The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3′′-bis(bromomethyl)-m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ ,μ-tpsac)]2, [Ru2(CO)4(μ ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2...
متن کاملThe Molecular Structure of 1 , 3 , 5 , 7 - Tetra ( tert - butyl ) - 2 , 4 , 6 , 8 - tetra ( chloro ) - borazocine [ 1 ]
The borazocine (ClB=NCMe3)4 crystallizes in the monoclinic system, space groupC2/c with Z = 6, i. e. there are two independent molecules in the unit cell. The first molecule has no crystallographic symmetry, while the second molecule is characterized by a twofold axis which generates the (ClB= NCMe3)4 molecule from the fragment (ClB=NCMe3)2. The molecules are tub-shaped showing alternating long...
متن کاملNew facets of an old ligand: titanium and zirconium complexes of phenylenediamine bis(phenolate) in lactide polymerisation catalysis.
Phenylenediamine bis(phenolate) binds in the reduced dianionic form to titanium and zirconium alkoxides giving either mononuclear or bridging dinuclear complexes depending on the metal precursors; the fluxional mononuclear titanium complex is found to exhibit extremely high activity in polymerisation of rac-lactide in the melt.
