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)...

1. INTRODUCTION Nitrogen-rich compounds are unique very reactive substances which have high heats of formation. Pyridine is one of the most well known aromatic cycles where a CH is replaced by a nitrogen atom, but the pyridine ring is only one member of the azine heterocycles, in which one or more CH group of benzene is replaced by π-accepting and σ-donating nitrogen atoms, proceeding from diaz...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Transition metal complexes bearing a 2,2-bis(3,5-dimethylpyrazol-1-yl)propionate ligand: one methyl more matters.
The new N,N,O ligand 2,2-bis(3,5-dimethylpyrazol-1-yl)propionic acid (2,2-Hbdmpzp) (2) and its transition metal complexes [Mn(2,2-bdmpzp)(CO)(3)] (3), [Re(2,2-bdmpzp)(CO)(3)] (4), [Cu(2,2-bdmpzp)(2)] (5), and [Ru(2,2-bdmpzp)Cl(L)(PPh(3))] [L = PPh(3) (6), N(2) (7), CO (8a/b), SO(2) (9a/b)] have been synthesized, characterized and compared to analogous complexes bearing a bis(3,5-dimethylpyrazol...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
