Synthesis, characterisation and theoretical studies on some piano-stool ruthenium and rhodium complexes containing substituted phenyl imidazole ligands

Reactions of the chloro-bridged arene ruthenium complexes [{(eta6-arene)RuCl(mu-Cl}2] (eta6-arene = benzene, p-cymene) and structurally analogous rhodium complex [{(eta5-C5Me5)RhCl(mu-Cl}2] with imidazole based ligands viz., 1-(4-nitro-phenyl)-imidazole (NOPI), 1-(4-formylphenyl)-imidazole (FPI) and 1-(4-hydroxyphenyl)-imidazole (HPI) have been investigated. The resulting complexes have been characterised by elemental analyses, IR, 1H and 13C NMR, electronic absorption and emission spectral studies. Crystal structure of the representative complex [(eta5-C5Me5)RhCl2(NOPI)] has been determined crystallographically. Geometrical optimisation on the complexes have been performed using exchange correlation functional B3LYP. Optimised bond lengths and angles of the complexes have been found to be in good agreement with our earlier reports and single crystal X-ray data of the complex [(eta5-C5Me5)RhCl2(NOPI)].

Ruthenium-catalyzed regioselective C-H alkenylation directed by a free amino group

The ruthenium-catalyzed alkenylation reactions of 2-aminobiphenyls and cumylamine proceed smoothly to produce the corresponding regioselectively alkenylated products. These reactions involve a C-H bond cleavage directed by their free amino groups.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Dichloro(benzene)ruthenium(II) dimer, you can also check out more blogs about37366-09-9

Stepwise Photoinduced Electron Transfer in a Tetrathiafulvalene-Phenothiazine-Ruthenium Triad

A molecular triad comprising a [Ru(bpy)3]2+ (bpy = 2,2?-bipyridine) photosensitizer, a primary phenothiazine (PTZ) donor and a secondary (extended) tetrathiafulvalene (exTTF) donor was synthesized and explored by UV/Vis transient absorption spectroscopy. Initial photoinduced electron transfer from PTZ to the 3MLCT-excited [Ru(bpy)3]2+ occurs within less than 60 ps, and subsequently PTZ is regenerated by electron transfer from exTTF with a time constant of 300 ps. The resulting photoproduct comprising exTTF¡¤+ and [Ru(bpy)3]+ has a lifetime of 6100 ps in de-aerated CH3CN at room temperature. Additional one- and two-pulse laser flash photolysis studies of the triad were performed in the presence of excess methyl viologen (MV2+), to explore the possibility of light-driven charge accumulation on exTTF. MV2+ clearly oxidized [Ru(bpy)3]+ and thereby re-instated ground-state [Ru(bpy)3]2+ in triads in which exTTF had been oxidized to exTTF¡¤+, but further excitation of the solution containing the exTTF¡¤+-PTZ-[Ru(bpy)3]2+ photoproduct did not provide evidence for exTTF2+. Nevertheless, it seems that the design principle of a covalent donor-donor-sensitizer triad (as opposed to simpler donor-sensitizer dyads) is beneficial for light-driven accumulation of oxidation equivalents. These investigations are relevant in the greater context of multi-electron photoredox chemistry and artificial photosynthesis.

Direct Catalytic Asymmetric Cyclopropylphosphonation Reactions of N,N-Dialkyl Groups of Aniline Derivatives by Ru(II)-Pheox Complex

Novel catalysis involving phosphonomethylation of N-methylaniline and asymmetric cyclopropylphosphonation reactions of N,N-diethylaniline derivatives with diazomethylphosphonates are reported. Optically active cyclopropylphosphonate derivatives were directly synthesized from diazomethylphosphonates and N,N-diethylaniline derivatives catalyzed by a Ru(II)-Pheox complex in one step in good yields and high diastereoselectivities (up to trans/cis = > 99:1<) and enantioselectivities (up to 99% ee). D-labeling mechanistic studies of phosphonomethylation and cyclopropylphosphonation suggested that an enamine or iminium intermediate was generated in the reaction process.

Novel platinum group metal complexes bearing bidentate chelating pyrimidyl-NHC and pyrimidyl imidazolyl-thione ligands: Syntheses, spectral and structural characterization

A family of novel platinum group metal complexes containing bidentate chelating 1-pyrimidyl-3-methylimidazolyl bromide (HL1¡¤Br) and 1-pyrimidyl-3-methylimidazolyl-2-thione (L2) ligands has been synthesized. The synthetic protocol for the formation of these complexes differs from one ligand to the other. Treatment of ligand (HL1¡¤Br) with the metal precursors led to the formation of complexes via in situ carbene transfer reactions. The silver-NHC complex (1) was formed by the reaction of HL1¡¤Br with silver oxide under light-free conditions. Subsequent addition of appropriate metal precursors to the silver-NHC complex yielded [(eta6-arene)Ru(L1)Cl] PF6 complexes {arene = C6H6 (2), p- iPrC6H4Me (3), C6Me6 (4)} on stirring at room temperature, whereas the complexes [CpRu(L1)(PPh 3)]PF6 {Cp = C5H5 (5), C 9H7 (6)} were obtained under reflux conditions. In the case of ligand L2, stirring of equimolar quantities of metal precursors and the ligand at room temperature yielded [(eta6-arene)Ru(L2)Cl]PF 6 {arene = C6H6 (7), p-iPrC 6H4Me (8), C6Me6 (9)}, and [Cp*M(L2)Cl]PF6 {Cp* = C5Me5, M = Rh (10), Ir (11)}. All these complexes were characterized by CHN analysis, IR, NMR and mass spectrometry besides confirmation by single crystal X-ray diffraction studies for some representative complexes as their hexafluorophosphate salts [3]PF6, [5]PF6, [8]PF 6 and [10]PF6.

Neutral chiral cyclopentadienyl Ru(ii)Cl catalysts enable enantioselective [2+2]-cycloadditions

Cyclopentadienyl ruthenium(ii) complexes with a large number of available coordination sites are frequently used catalysts for a broad range of transformations. To be able to render these transformations enantioselective, we have designed a chiral neutral CpxRu(ii)Cl complex basing on an atropchiral cyclopentadienyl (Cpx) ligand which is accessed in a streamlined C-H functionalisation approach. The catalyst displays excellent levels of reactivity and enantioselectivity for enantioselective [2+2]-cycloadditions leading to strained chiral cyclobutenes, allowing for catalyst loadings as low as 1 mol%. A very strong counterion effect of a bound chloride anion transforms the corresponding unselective cationic complex into a highly enantioselective neutral version. Moreover, by adding norbornadiene at the end of the reaction the catalyst can be recovered and subsequently reused.

Selective hydrogenation of ruthenium acylphosphine complexes

Hydrogenation of a benzene ruthenium chloride dimer in the presence of novel acylphosphine (phosphomide) ligands resulted in the formation of corresponding ruthenium(II)-benzyl phosphine complexes. Here, selective reduction of the carbonyl group to a methylene unit takes place with molecular hydrogen under mild conditions in good yield. This approach provides an alternative synthesis of ruthenium phosphine complexes of benzyl and heterobenzyl phosphine ligands.
