Enantioselective transfer hydrogenation of pro-chiral ketones catalyzed by novel ruthenium and iridium complexes of well-designed phosphinite ligand

The interaction of [Ru(eta6-arene)(mu-Cl)Cl]2 and Ir(eta5-C5Me5)(mu-Cl)Cl]2 with a new Ionic Liquid-based phosphinite ligand, [(Ph2PO)-C6H9N2Ph]Cl, (2) gave [Ru((Ph2PO)-C6H9N2Ph)(eta6-p-cymene)Cl2]Cl (3), [Ru((Ph2PO)-C6H9N2Ph)(benzene)Cl2]Cl (4) and [Ir((Ph2PO)-C6H9N2Ph)(C5Me5)Cl2]Cl (5), complexes. All the compounds were characterized by a combination of multinuclear NMR and IR spectroscopy as well as elemental analysis. Furthermore, the Ru(II) and Ir(III) catalysts were applied to asymmetric transfer hydrogenation of acetophenone derivatives using 2-propanol as a hydrogen source. The results showed that the corresponding alcohols could be obtained with good activity (up to 55% ee and 99% conversion) under mild conditions. Notably, [Ir((Ph2PO)-C6H9N2Ph)(C5Me5)Cl2]Cl (5) is more active than the other analogous complexes in the transfer hydrogenation (up to 81% ee).

A variable temperature NMR analysis and resonance assignment of the Grubbs second generation catalyst

The Grubbs second generation catalyst [RuCl2(PCy3)(H2IMes)CHPh] was analysed in solution in order to identify and assign all of the 1H and 13C NMR resonances. This was achieved through utilizing various 2D NMR techniques and by acquiring spectra at a range of different temperatures (?40 to 60 C). These assignments will aid researchers in future NMR studies of catalytic systems that employ the Grubbs catalyst by eliminating the resonances belonging to the catalyst and thus enabling the identification of any intermediates and/or new catalytic species. Restricted conformations and pi-stacking arrangement within the catalyst was also confirmed during this study.

Modular Synthesis of Diverse Natural Product-Like Macrocycles: Discovery of Hits with Antimycobacterial Activity

A modular synthetic approach was developed in which variation of the triplets of building blocks used enabled systematic variation of the macrocyclic scaffolds prepared. The approach was demonstrated in the synthesis of 17 diverse natural product-like macrocyclic scaffolds of varied (12?20-membered) ring size. The biological relevance of the chemical space explored was demonstrated through the discovery of a series of macrocycles with significant antimycobacterial activity.

Red and blue luminescent metallo-supramolecular coordination polymers assembled through pi-pi interactions

The use of pi-stacking interactions to control the aggregation of photo-active metal centres is explored through the design of bis(2,2?;6?,2?-terpyridyl) metal complexes functionalised with biphenyl ‘tails’. Aryl-aryl interactions control the aggregation of the metal complexes into polymetallic arrays in the solid state. Cobalt(n), ruthenium(n), nickel(n), copper(n), zinc(n) and cadmium(n) bis-ligand complexes and a mixed ligand ruthenium(n) complex have been structurally characterised. The solid-state structures are dependent on which units dominate the pi-stacking. For cobalt, ruthenium, nickel and copper, biphenylene-biphenylene interactions lead to linear rod-like arrays, while for the group 12 d10 ions zinc and cadmium, biphenylene-pyridyl interactions lead to two-dimensional sheets. The addition of the biphenylene tail has favourable effects on the photophysical-properties of the complexes which exhibit room temperature red (ruthenium) or blue (zinc and cadmium) luminescence, both in solution and the solid state.

Difluoromethylation of Terminal Alkynes by Fluoroform

The difluoromethylation of terminal alkynes through the use of fluoroform as a source of difluorocarbene is described. The choice of solvents and bases was found to be crucial for the transformation. A series of terminal alkynes 1 were nicely converted into the corresponding difluoromethyl alkynes 2 using potassium tert-butoxide in n-decane in moderate to good yields. Functional groups such as methoxy, dimethylamino, and bromo as well as phenyl, heteroaryl, and sterically demanding naphthyl were well tolerated under the reaction conditions. One-step transformations of difluoromethyl alkynes 2 to difluoromethylated isoxazoles 3 and 1,2,3-triazoles 4 were also achieved.

Mechanistic investigations on the hydrogenation of alkenes using ruthenium(II)-arene diphosphine complexes

The ruthenium(II) complexes [Ru(eta2-P-P)(eta6-p- cymene)Cl]Cl, P-P = diphenylphosphinomethane (dppm), diphenylphosphinoethane (dppe), or diphenylphosphinopropane (dppp), and the highly water-soluble analogues, [Ru(eta2-P-P)(eta6-arene)Cl]Na3, P-P = 1,2-bis(di-4-sulfonatophenylphosphino)benzene (dppbts), arene = p-cymene, benzene, or [2.2]paracyclophane, are efficient catalyst precursors for the hydrogenation of styrene in an aqueous biphase. By the use of high gas pressure NMR techniques and electrospay ionization mass spectrometry, the active species in the hydrogenation have been indirectly identified to be a dihydrogen complex, which also catalyzes H/D isotope exchange. Using the ruthenium(II) dppbts derivatives as precatalysts, evidence is provided for an arene exchange process that takes place during the catalytic hydrogenation of styrene. Together, these results lead to the proposition of a catalytic cycle for the hydrogenation of the C=C double bond of styrene using ruthenium(II)-arene diphosphine complexes.

Enyne metathesis for the formation of macrocyclic 1,3-dienes

Macrocyclic 1,3-dienes of a variety of ring sizes are formed in good yield via enyne metathesis. Both endo- and exo-products are observed depending on the size of the macrocycle. In general, 10-membered rings and smaller give exo-products, while 12-membered rings and larger give endo-products. The endo/exo selectivity and the E/Z ratio of the diene products can be further controlled by the presence of ethylene in the reaction. Copyright

Stereoselective synthesis of the C1-C8 subunit of peloruside A

Two routes to the C1-C8 subunit of peloruside A are disclosed. The first route involving 14 steps exploits Krische’s allylation, substrate controlled 1,3-asymmetric induction during bromohydrin formation from an alkene utilizing an intramolecular sulfinyl group as a nucleophile and Pummerer reaction as key steps. The second, shorter, scalable route (seven steps) exploits catalytic asymmetric reactions including Jacobsen’s hydrolytic kinetic resolution of an epoxide and Sharpless’ asymmetric dihydroxylation reaction as the key steps.

Long Range Photoinduced Electron Transfer in a Rigid Polymer

Electron (hole) tunnelling reactions are studied in a rigid polymer medium by following the reductive quenching of a series of Ru(LL)3(2+)* homologues by a series of aromatic amines.Tunnelling distances up to 12 Angstroem (edge to edge) are observed.The experimental data include a determination of the exponential damping factor alpha in the electronic term (Hab).The data are consistent with a weak dependence of alpha on binding energy.Such a weak dependence is more consistent with a superexchange description than with a barrier tunnelling description of electron (hole) transfer.These reactions are shown to be essentially temperature independent between 298 K and 359 K, but are significantly slower at 77 K.

Synthesis of ruthenium vinylidene complexes with dppe ligand and their cyclopropenation reaction

A number of cationic ruthenium vinylidene complexes [Ru]=C=C(Ph)CH2R+ ([Ru]=(eta5-C5H5)(dppe)Ru, dppe=Ph2PCH2CH2PPh2, 5a, R=CN; 5b, R=C6F5; 5c, R=Ph; 5d, R=p-C6H4CN; 5e, R=p-C6H4CF3; 5f, R=1-C10H7; 5g, R=CO2CH3) are prepared from electrophilic addition of organic halides to the acetylide complex [Ru]-CCPh at the boiling point of CHCl3. Complex 5g?, prepared at room temperature, displays similar spectroscopic property as that of 5g but is easily hydrolyzed to give [Ru]COCH2Ph (6). Cyclopropenation of the organic vinylidene moiety of 5a-5f is accomplished in acetone by deprotonation of 5 with n-Bu4NOH yielding the neutral cyclopropenyl complexes (7a, R=CN; 7b, R=C6F5; 7c, R=Ph; 7d, R=p-C6H4CN; 7e, R=p-C6H4CF3; 7f, R=1-10H7). Protonation of 7b-7f regenerates the corresponding vinylidene complexes. In the presence of allyl iodide, opening of the three-membered ring of 7a, followed by a subsequent oxidative coupling reaction, gives a dimeric dicationic product {[Ru]=C=C(Ph)-CHCN}2+2 (9a). In the processes of preparing the starting material Cp(dppe)RuCl for the acethylide complex, two dppe complexes Ru(dppe)2Cl2 (2) and [Cp(dppe)RuCl]2 (3) are isolated. Molecular structures of complexes 2, 3, 6, and 7b have been confirmed by X-ray diffraction analysis.
