Water-soluble ruthenium(II) catalysts [RuCl2(eta6- arene)-{P(CH2OH)3}] for isomerization of allylic alcohols and alkyne hydration

The novel water-soluble ruthenium(II) complexes [RuCl 2(eta6-arene){P(CH2OH)3}] 2a-c and [RuCl(eta6-arene){P(CH2OH)3} 2][Cl] 3a-c have been prepared in high yields by reaction of dimers [{Ru(eta6-arene)(mu-Cl)Cl}2] (arene = C 6H6 1a, p-cymene 1b, C6Me6 1c) with two or four equivalents of P(CH2OH)3, respectively. Complexes 2/3a-c are active catalysts in the redox isomerization of several allylic alcohols into the corresponding saturated carbonyl compounds under water/n-heptane biphasic conditions. Among them, the neutral derivatives [RuCl2(eta6-C6H6){P(CH 2OH)3}] 2a and [RuCl2(eta6-p- cymene){P(CH2OH)3}] 2b show the highest activities (TOP values up to 600 h-1; TON values up to 782). Complexes 2/3a-c also catalyze the hydration of terminal alkynes.

Synthesis of ruthenium-hydride complexes and preparation procedures of chiral alcohols and ketones

trans-RuH(eta1-BH4)[(S)-xylbinap][(S,S)-dpen] (0.00125 mmol), acetophenone (5.0 mmol), and 2-propanol (2.5 mL) were placed in an autoclave, and the resulting solution was repeatedly subject 5 times to a procedure of performing pressure reduction and argon introduction while stirring the solution for deaeration. A hydrogen tank was then connected to the autoclave, and after replacing the air inside an introduction tube with hydrogen, the pressure inside the autoclave was adjusted to 5 atmospheres and then hydrogen was released until the pressure dropped to 1 atmosphere. After repeating this procedure 10 times, the hydrogen pressure was adjusted to 8 atmospheres and stirring at 25 C. was performed for 12 hours. By concentrating the solution obtained by depressurization and subjecting the crude product to simple distillation, (R)-1-phenylethanol (yield: 95%) in the form of a colorless oily substance was obtained at an ee of 99%.

The unstable compounds [(eta6-arene)RuCl2(kappaP-PPh2(2-C6H4CO2CH2CH2OCO-EA))] (arene = p-cymene, 5a; arene = C6H6, 5b) were obtained and identified in solution by NMR. Electrochemical and spectro-electrochemical experiments were performed in order to assess the redox behaviour of 1-4 in CH2Cl2. The in vitro cytotoxicity of 1-4 was determined on the human pancreatic cancer cell line BxPC3 and the mouse embryo fibroblast Balb/3T3 Clone A31 cell line, the latter acting as a model for normal cells. Furthermore, the interaction of 1, 3 and 4 with two model proteins was investigated by high resolution ESI-MS.

Influence of increasing steric demand on isomerization of terminal alkenes catalyzed by bifunctional ruthenium complexes

Preparation of a series of cyclopentadienyl- and imidazolyl-phosphine-containing Ru-based complexes bearing a different degree of the Cp-ring methylation has been attempted. According to experimental and structural data the steric factors prevented the formation of the last complex in the series that contains permethylated Cp ring. These complexes were then subjected to alkene isomerization using 1-hexene. The rate of isomerization decreased, in general, with the increase in the Cp-ring methylation suggesting that the initial alkene coordination and/or imidazolyl N decoordination steps are restricted in the overall mechanism.

Design of Ru(II)-NHC-Diamine Precatalysts Directed by Ligand Cooperation: Applications and Mechanistic Investigations for Asymmetric Hydrogenation

A modular synthesis of Ru(II)-NHC-diamine complexes from readily available chiral N-heterocyclic carbenes (NHCs) and chiral diamines is disclosed for the first time. The well-defined Ru(II)-NHC-diamine complexes show unique structure and coordination chemistry including an unusual tridentate coordination effect of 1,2-diphenylethylenediamine. The isolated air- A nd moisture-stable Ru(II)-NHC-diamine complexes act as versatile precatalysts for the asymmetric hydrogenation of isocoumarines, benzothiophene 1,1-dioxides, and ketones. Moreover, on the basis of the identification of reaction intermediates by stoichiometric reactions and NMR experiments, together with the DFT calculations, a possible catalytic cycle was proposed.

The tripodal, tetradentate tris(1-(diphenylphosphanyl)-3-methyl-1H-indol-2-yl)phosphane PP3-ligand 1 stabilizes Ru in the RuII, RuI, and Ru0 oxidation states. The octahedral [(PP3)RuII(Cl)2] (2), distorted trigonal bipyramidal [(PP3)RuI(Cl)] (3), and trigonal bipyramidal [(PP3)Ru0(N2)] (4) complexes were isolated and characterized by single-crystal X-ray diffraction, NMR, EPR, IR, and ESI-MS. Both open-shell metalloradical RuI complex 3 and the closed-shell Ru0 complex 4 undergo facile (net) abstraction of a Cl atom from dichloromethane, resulting in formation of the corresponding RuII and RuI complexes 2 and 3, respectively.
