Cycloruthenated complexes of the type [(eta6-C6H6)Ru(C?N)CH3CN] +PF6- (C&N = C6H4-2-CH2NMe2, (R)-(+)-C6H4-2-CH(Me)NMe2,C6H 2-3,4-(OCH3)2-2-CH2-NMe2) are readily obtained by the intramolecular C-H activation of N,N-dimethylbenzylamine derivatives with [(eta6-C6H6)RuCl2l2 in up to 53% isolated yields. Under similar conditions, 8-methylquinoline also led to a cycloruthenated complex, though in lower yield (12%) and after a longer reaction time. Reaction with the optically active (R)-(+)-N,N-dimethyl-1-phenylethylamine led to a 48% diastereomeric excess in the cycloruthenated product. Under the same conditions, and after 14 and 65 h of reaction time, respectively, 2-phenyl- and 2-benzylpyridine are cyclometalated, leading to the formation of complexes in which the benzene ligand has been substituted by three acetonitriles: [(CAN)Ru(CH3CN)+PF6- (C?N = C6H4-2-C5H4N, C6H4-2-(CH2)-C5H4N) were obtained in 40 and 24% isolated yields, respectively.

Coordinatively unsaturated 16-electron ruthenium-selenolate complexes (eta6-arene)Ru(Se-2,4,6-C6H2Me3)2 [arene = p-CH3C6H4(CHMe2) (5b), C6Me6 (5c)] have been prepared by treating [((eta6-arene)RuCl2]2 (1) with sodium salt of 2,4,6-trimethylphenyl-selenolate in methanol. The complexes 5 are compared with the thiolate complexes such as (eta6-arene)Ru(SAr)2 [SAr = 2,6-dimethylbenzenethiolate (2), SAr = 2,4,6-tri(isopropyl)benzenethiolate (3), (SAr)2 = 1,2-benzenedithiolate (4); arene = C6H6 (a), p-CH3C6H4(CHMe2) (b), C6Me6 (c)], which have been recently prepared by us. However, the tellurolate analog has not been obtained in similar manner. These selenolate complexes are dark green, being ascribed to the LMCT band [ppi(Se) ? dpi * (Ru)]. The absorption bands of 5 are red-shifted compared to the thiolate complexes. In contrast to the bulky substituted chalcogenolate ligand system, the reaction of 1 with PhENa followed by the addition of KPF6 resulted in the formation of the cationic binuclear chalcogenolate complexes [(etaeta6-arene)Ru(mu-E-Ph)3Ru(eta6-arene)](PF6) [E = Se (7), E = Te (8); arene = p-CH3C6H4(CHMe2) (b), C6Me6 (c)]. Reactions of the 16-electron thiolate and selenolate complexes with sigma-donor molecules such as DMSO, hydrazine and ammonia along with some electrophiles were investigated. DMSO can coordinate with the thiolate complex 2a to give a DMSO adduct of 9, which was characterized spectroscopically and crystallographically. The strength of complexation of hydrazine and ammonia to the thiolate and selenolate complexes 2, 3, 4c and 5 depends on the effective electron deficiency of the ruthenium supported by eta6-arene ligand and two chalcogenolate ligands. Two new hydrazine complexes (eta6-C6H6)Ru(eta1-NH2NH2)(S-2,6-C6H3Me2)2 (10a) and [(eta6-C6Me6)Ru(S2C6H4)]2( mu-NH2NH2) (16) were crystallographically characterized. The observed two different coordination modes, mononuclear eta1-hydrazine and binuclear mu-hydrazine, were the results of the combined steric effect of the arene and the thiolate coligands as well as the NH … S hydrogen bonding.

Carbohydrate ligands have been studied in transition-metal-catalyzed hydrogenations in recent decades. Herein, we report the diastereoselective synthesis of trans-dichlorido(bisphosphane)ruthenium(II) complexes with four different methyl 2,3-diamino-4,6-O-benzylidene-2,3-dideoxy-alpha-D-hexopyranosides and their application as catalyst precursors in asymmetric hydrogenation reactions. Depending on the hexopyranose, an enantiomeric excess of up to 78 % was obtained. The Noyori-type hydrogenation catalyst precursor is modified with methyl 2,3-diamino-4,6-O-benzylidene-2,3-dideoxy-alpha-D-hexopyranoside ligands (glucose, mannose, gulose, and talose). The trans-dichloridoruthenium(II) complexes are diastereoselectively formed. Enantiomeric excesses of up to 78 % are obtained in enantioselective hydrogenation reactions under normal hydrogen pressure.

Reaction of the bis-bidentate ligand, 1,3-bis((3-(pyridin-2-yl)-1H-pyrazol-1-yl)methyl)benzene (NN?NN), containing two chelating pyrazolyl-pyridine units connected by an aromatic spacer with platinum group metal complexes results in a series of cationic binuclear complexes, [(eta6-arene)2Ru2(NN?NN)Cl2]2+ (arene = C6H6, 1; p-iPrC6H4Me, 2; C6Me6, 3), [(eta5-C5Me5)2M2(NN?NN)Cl2]2+ (M = Rh, 4; Ir, 5), [(eta5-C5H5)2M2(NN?NN)(PPh3)2]2+ (M = Ru, 6; Os, 7), [(eta5-C5Me5)2Ru2(NN?NN)(PPh3)2]2+ (8) and [(eta5-C9H7)2Ru2(NN?NN)(PPh3)2]2+ (9). All these complexes have been isolated as their hexafluorophosphate salts and fully characterized by use of a combination of NMR spectroscopy, IR spectroscopy and mass spectrometry. The solid state structures of three complexes, [2][PF6]2, [4][PF6]2 and [6][PF6]2, has been determined by X-ray crystallographic studies.

Three different series of novel mononuclear arene-ruthenium(II) complexes containing amino-phosphine ligands, namely, [RuCl2{kappa 1(P)-2-Ph2PC6H4CH 2NHR}(eta6-arene)], [RuCl2{kappa 1(P)-3-Ph2PC6H4CH 2NHR}(eta6-arene)], and [RuCl2{kappa 1(P)-4-Ph2PC6H4CH 2NHR}(eta6-arene)] (arene = C6H6, p-cymene, 1,3,5-C6H3Me3, C6Me 6; R = iPr, tBu; all combinations), have been synthesized and fully characterized. These readily accessible species are efficient catalysts for the selective hydration of organonitriles into amides under challenging reaction conditions, i.e., pure aqueous medium in the absence of any cocatalyst, being much more active than their corresponding nonfunctionalized triphenylphosphine counterparts [RuCl2(PPh 3)(eta6-arene)]. The results obtained in this study indicate that the (amino-phosphine)ruthenium(II) complexes operate through a “bifunctional catalysis” mechanism in which the ruthenium center acts as a Lewis acid, activating the nitrile molecule, and the P-donor ligand acts as a Brnsted base, the pendant amino group generating the real nucleophile of the hydration process, i.e., the OH- group.

A highly chemo- and enantioselective hydrogenation of beta-diketones was achieved by using [Ru(benzene)(S)-SunPhosCl]Cl for consistency in THF. The neighboring heteroatoms played important roles in guaranteeing the reactivity and controlling the chemoselectivity. These results suggested a potential approach for the clean and facile synthesis of functionalized chiral beta-hydroxy ketones, which could otherwise be prepared through much less step-economic transformations.

The benzene-Ru(II)-supported trilacunary heteropolytungstates [(RuC 6H6)2XW9O34] 6- (X = Si, 1; Ge, 2) have been synthesized and characterized by multinuclear solution NMR (183W, 13C, 1H, 29Si), UV-vis and IR spectroscopy, electrochemistry, and elemental analysis. Single-crystal X-ray analysis was carried out on Rb2Na 4[(RuC6H6)2SiW9O 34]· 21H2O (RbNa-1), which crystallizes in the triclinic system, space group P1, with a = 11.9415(2) A, b = 13.3123(2) A, c = 19.4927(4) A, alpha = 96.6460(10), beta = 95.1570(10), gamma = 98.2560(10), and Z = 2 and on Cs 2Na4-[(RuC6H6)2GeW 9O34]·19.5H2O (CsNa-2), which crystallizes also in the triclinic system, space group P1, with a = 11.930(4) A, b = 13.353(4) A, c = 19.586(6) A, alpha = 95.982(5), beta = 95.414(6), gamma = 98.142(5), and Z = 2. The novel polyanion structure consists of two (RuC6H6) units linked to a trilacunary (XW9O34) Keggin fragment via Ru-O(W) and Ru-O(X) bonds resulting in an assembly with Cs symmetry. Polyanions 1 and 2 were synthesized by reaction of [RuC6H6Cl 2]2 with [A-alpha-XW9O34] 10- in aqueous buffer medium (pH 6.0). Both 1 and 2 are stable in solution as indicated by the expected 5-line pattern (2:1:2:2:2) in the 183W NMR and the expected 13C, 1H, and 29Si spectra. Descriptions of the respective electrochemical behaviors of the W centers and the Ru centers in 1 and 2 are given in media where these processes are clearly defined. In a pH = 3 acetate medium, the cyclic voltammetry of the W centers shows the known fingerprint of the trilacunary alpha-[XW9O34]n- (X = Ge, Si) moieties. The presence of the (RuC6H6) substituents imparts a good stability to these fragments in solution. Stepwise oxidation of the Ru centers was suspected in pH = 5 acetate medium, but only the first step was well-separated from a large current composite wave. The stepwise oxidation was finally observed clearly in a DMF-water (90/10 v/v) mixture and shows two well-behaved Ru oxidation processes. A short comparison is made with DMSO-bearing Ru polyoxometalates.

Parahydrogen (p-H2) induced polarization (PHIP) NMR spectroscopy showed that [CpXRu] complexes with greatly different electronic properties invariably engage propargyl alcohol derivatives into gem-hydrogenation with formation of pianostool ruthenium carbenes; in so doing, less electron rich CpX rings lower the barriers, stabilize the resulting complexes and hence provide opportunities for harnessing genuine carbene reactivity. The chemical character of the resulting ruthenium complexes was studied by DFT-assisted analysis of the chemical shift tensors determined by solid-state 13C NMR spectroscopy. The combined experimental and computational data draw the portrait of a family of ruthenium carbenes that amalgamate purely electrophilic behavior with characteristics more befitting metathesis-active Grubbs-type catalysts.

A range of TsDPEN catalysts containing heterocyclic groups on the amine nitrogen atom were prepared and evaluated in the asymmetric transfer hydrogenation of ketones. Bidentate and tridentate ligands demonstrated a mutual exclusivity directly related to their function as catalysts. A broad series of ketones were reduced with these new catalysts, permitting the ready identification of an optimal catalyst for each substrate and revealing the subtle effects that changes to nearby donor groups can exhibit.
