Synthesis, isolation and spectroscopic characterization of Dawson polyoxotungstate-supported, organometallic complex, [{(C6H6)Ru}P2W15V3O62]7-: The two positional isomers

The Dawson polyoxotungstate (POM)-based, organometallic ruthenium(II) complex, [{(C6H6)Ru}P2W15V3O62]7-, was synthesized as two materials, i.e. 1 ¡¤ 2Bu4NCl and 1 ¡¤ 1Bu4NCl (1 = (Bu4N)7[{(C6H6)Ru}P2W15V3O62]), which contained two positional isomers a and b as major or minor species. In isomer a with the overall Cs symmetry, the (C6H6)Ru2+ group was supported on one vanadium(V) octahedral site (two V-O-V bridging oxygens and one O{double bond, long}V terminal oxygen) of the three edge-shared vanadium(V) octahedra (V3 site, B-site) in the Dawson POM-support [1,2,3-P2W15V3O62]9-, whereas in the other isomer b with the overall C3v symmetry, the (C6H6)Ru2+ group was supported on the center of the V3 site in the Dawson POM-support. Material 1 ¡¤ 2Bu4NCl was prepared by a stoichiometric reaction in CH2Cl2 at ambient temperature of the Dawson POM-support (Bu4N)9[1,2,3-P2W15V3O62] with the precursor [(C6H6)RuCl2]2, whereas material 1 ¡¤ 1Bu4NCl was prepared by a stoichiometric reaction in CH3CN under refluxing conditions. The temperature-varied 31P NMR spectra revealed that b was thermodynamically more stable thana.

Extraction of rutheniumd(III) by bis(butylthioethyl)amine from hydrochloric acid solutions

A polyfunctional sulfur- and nitrogen-containing reagent, bis(butylthioethyl) amine (L), was used as an extradant of ruthenium(III). Optimum conditions for the extraction of ruthenium(III) were determined. It was found that an ion-exchange mechanism of ruthenium(III) extraction took place in the extraction system at a phase contact time of 10 min or shorter. As the phase contact time was longer than 10 min, the extraction took place by a solvation mechanism as inner-sphere substitution with the formation of neutral coordinatively solvated complexes. The composition of the extracted compounds was suggested based on electronic absorption, 1H NMR, and IR spectroscopy and elemental analysis. Copyright

Pd-Catalyzed C-3 functionalization of indolizines via C-H bond cleavage

New transition metal-catalyzed methods for the arylation of indolizines by the direct cleavage of C-H bonds have been developed. A wide range of aryltrifluoroborate salts react with indolizines in the presence of Pd(OAc) 2 catalyst and AgOAc oxidant to give the arylated indolizines in high yields. Both electron-donating and electron-withdrawing groups perform smoothly while bromide and chlorine substituents are tolerated. In addition, the indolizines display similar reactivities in the Pd-catalyzed reaction with 3-phenylpropiolic acid to afford the corresponding C-3 alkynylated indolizines. These methods allow the direct functionalization of indolizines in one step.

Highly enantioselective hydrogenation of steric hindrance enones catalyzed by Ru complexes with chiral diamine and achiral phosphane

An asymmetric hydrogenation of sterically hindered beta,beta- disubstituted enones has been well-established by using a ruthenium complex composed of an achiral diphosphane and a chiral diamine as catalyst, wherein the carbonyl group was selectively hydrogenated to give a wide range of chiral allylic alcohols with high levels of enantioselectivity and complete chemoselectivity.

Chiral 1,2-bis(phosphetano)ethanes

Optically pure 1,2-bis(phosphetano)ethanes 3 (BPE-4) have been prepared from 1,2-bis(phosphino)ethane and the cyclic sulfates of symmetrical anti-1,3-diols. Diphosphine 3c (R = cyclohexyl) is an easily accessible, air-stable chiral ligand. Its suitability to the ruthenium-catalysed hydrogenation of functionalised ketones has been examined by using several catalyst precursors. Significant enantiomeric excesses were obtained. A ruthenium complex containing two coordinated diphosphines 3c was characterised by X-ray diffraction studies.
