Conjugated microporous polymers with chiral BINAP ligand built-in as efficient catalysts for asymmetric hydrogenation

A series of chiral conjugated microporous polymers (CMPs) based on the chiral (R)-BINAP ligand (BINAP-CMPs) were synthesized with tunable BET surface areas. These solid catalysts show high activities and enantioselectivities for the asymmetric hydrogenation of beta-keto esters after coordination with ruthenium species. Moreover, CMPs can realize spatial isolation. Through preventing the formation of dimers and trimers, BINAP-CMPs show much higher activity than BINAP for the Ir-catalyzed asymmetric hydrogenation of quinaldine.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Synthetic Route of 37366-09-9

Synthesis and excited-state propertdies of a novel ruthenium nucleoside: 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine

The synthesis and photophysical properties of a novel ruthenium-modified nucleoside are reported. The key synthetic step to 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine involves the Pd(0)-catalyzed cross-coupling of a propargylamine-derivatized Ru(bpy)32+ and 3?,5?-dibenzoyloxy-2?-deoxy-5-iodouridine. The long-lived 3MLCT excited state (1300 ns) of 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine has an emission maximum centered at 640 nm. Step-scan Fourier transform infrared (S2FTIR) time-resolved spectroscopy reveals the excited-state electron to be localized on the modified bipyridine with the excited-state dipole oriented toward the 2?-deoxyuridine.

Interfacial energy conversion in RuII polypyridyl-derivatized oligoproline assemblies on TiO2

Solid-phase peptide synthesis has been applied to the preparation of phosphonate-derivatized oligoproline assemblies containing two different Ru II polypyridyl chromophores coupled via “click” chemistry. In water or methanol the assembly adopts the polyproline II (PPII) helical structure, which brings the chromophores into close contact. Excitation of the assembly on ZrO2 at the outer RuII in 0.1 M HClO 4 at 25 C is followed by rapid, efficient intra-assembly energy transfer to the inner RuII (kEnT = 3.0 ¡Á 10 7 s-1, implying 96% relative efficiency). The comparable energy transfer rate constants in solution and on nanocrystalline ZrO 2 suggest that the PPII structure is retained when bound to ZrO 2. On nanocrystalline films of TiO2, excitation at the inner RuII is followed by rapid, efficient injection into TiO 2. Excitation of the outer RuII is followed by rapid intra-assembly energy transfer and then by electron injection. The oligoproline/click chemistry approach holds great promise for the preparation of interfacial assemblies for energy conversion based on a family of assemblies having controlled compositions and distances between key functional groups.

Visible light-mediated oxidative quenching reaction to electron-rich epoxides: Highly regioselective synthesis of alpha-bromo (di)ketones and mechanism study

A novel and simple procedure was developed for the regioselective synthesis of alpha-bromo (di)ketones from electron-rich epoxides via visible light photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved under mild conditions. Moreover, the possible reaction mechanism was proposed and further supported by control experiments.

Synthesis and characterisation of bis(2,2?-bipyridine)(4-carboxy-4?-(pyrid-2-ylmethylamido)-2,2?-bipyridine)ruthenium(II) di(hexafluorophosphate): Comparison of spectroelectrochemical properties with related complexes

The new complex, [RuII(bpy)2(4-HCOO-4?-pyCH2 NHCO-bpy)](PF6)2 ¡¤ 3H2O (1), where 4-HCOO-4?-pyCH2NHCO-bpy is 4-(carboxylic acid)-4?-pyrid-2-ylmethylamido-2,2?-bipyridine, has been synthesised from [Ru(bpy)2(H2dcbpy)](PF6)2 (H2dcbpy is 4,4?-(dicarboxylic acid)-2,2?-bipyridine) and characterised by elemental analysis and spectroscopic methods. An X-ray crystal structure determination of the trihydrate of the [Ru(bpy)2(H2dcbpy)](PF6)2 precursor is reported, since it represented a different solvate to an existing structure. The structure shows a distorted octahedral arrangement of the ligands around the ruthenium(II) centre and is consistent with the carboxyl groups being protonated. A comparative study of the electrochemical and photophysical properties of [RuII(bpy)2(4-HCOO-4?-pyCH2NHCO-bpy)]2+ (1), [Ru(bpy)2(H2dcbpy)]2+ (2), [Ru(bpy)3]2+ (3), [Ru(bpy)2Cl2] (4) and [Ru(bpy)2Cl2]+ (5) was then undertaken to determine their variation upon changing the ligands occupying two of the six ruthenium(II) coordination sites. The ruthenium(II) complexes exhibit intense ligand centred (LC) transition bands in the UV region, and broad MLCT bands in the visible region. The ruthenium(III) complex, 5, displayed overlapping LC bands in the UV region and a LMCT band in the visible. 1, 2 and 3 were found, via cyclic voltammetry at a glassy carbon electrode, to exhibit very positive reversible formal potentials of 996, 992 and 893 mV (versus Fc/Fc+) respectively for the Ru(III)/Ru(II) half-cell reaction. As expected the reversible potential derived from oxidation of 4 (-77 mV (versus Fc/Fc+)) was in excellent agreement with that found via reduction of 5 (-84 mV (versus Fc/Fc+)). Spectroelectrochemical experiments in an optically transparent thin-layer electrochemical cell configuration allowed UV-Vis spectra of the Ru(III) redox state to be obtained for 1, 2, 3 and 4 and also confirmed that 5 was the product of oxidative bulk electrolysis of 4. These spectrochemical measurements also confirmed that the oxidation of all Ru(II) complexes and reduction of the corresponding Ru(III) complex are fully reversible in both the chemical and electrochemical senses.

Unusual photophysical properties of a ruthenium(II) complex related to [Ru(bpy)2(dppz)]2+

A new ruthenium polypyridyl complex, [Ru(bpy)2(dpqp)] 2+ (bpy = 2,2?-bipyridne; dpqp = pyrazino[2?,3?:5, 6]pyrazino[2,3-f][1,10]phenanthroline), shows strong luminescence in water at room temperature, a behavior that is strikingly different from that of the nonemissive “DNA light-switch” prototype [Ru(bpy)2(dppz)] 2+ (dppz = dipyrido[3,2-a:2?-3?-c]phenazine) under similar conditions. Variation of the absorption and emission spectra of [Ru(bpy)2(dpqp)]2+ as a function of the pH is consistent with the occurrence of two ground-state protonation steps associated with the dpqp ligand and an apparent pKa* of 2.1. Electrochemistry and theoretical calculations indicate that the lowest unoccupied molecular orbital (LUMO) of [Ru(bpy)2(dpqp)]2+ is localized on the distal portion of the dpqp ligand and lies at a lower energy than the dppz-based LUMO of [Ru(bpy)2(dppz)]2+. The combination of its strong DNA binding affinity and relatively long-lived triplet metal-to-ligand charge-transfer excited state in an aqueous solution results in more efficient DNA photocleavage by [Ru(bpy)2(dpqp)]2+ than [Ru(bpy) 2(dppz)]2+.

A study of transition-metal organometallic complexes combining 35Cl solid-state NMR spectroscopy and 35Cl NQR spectroscopy and first-principles DFT calculations

A series of transition-metal organometallic complexes with commonly occurring metal-chlorine bonding motifs were characterized using 35Cl solid-state NMR (SSNMR) spectroscopy, 35Cl nuclear quadrupole resonance (NQR) spectroscopy, and first-principles density functional theory (DFT) calculations of NMR interaction tensors. Static 35Cl ultra-wideline NMR spectra were acquired in a piecewise manner at standard (9.4 T) and high (21.1 T) magnetic field strengths using the WURST-QCPMG pulse sequence. The 35Cl electric field gradient (EFG) and chemical shielding (CS) tensor parameters were readily extracted from analytical simulations of the spectra; in particular, the quadrupolar parameters are shown to be very sensitive to structural differences, and can easily differentiate between chlorine atoms in bridging and terminal bonding environments. 35Cl NQR spectra were acquired for many of the complexes, which aided in resolving structurally similar, yet crystallographically distinct and magnetically inequivalent chlorine sites, and with the interpretation and assignment of 35Cl SSNMR spectra. 35Cl EFG tensors obtained from first-principles DFT calculations are consistently in good agreement with experiment, highlighting the importance of using a combined approach of theoretical and experimental methods for structural characterization. Finally, a preliminary example of a 35Cl SSNMR spectrum of a transition-metal species (TiCl4) diluted and supported on non-porous silica is presented. The combination of 35Cl SSNMR and 35Cl NQR spectroscopy and DFT calculations is shown to be a promising and simple methodology for the characterization of all manner of chlorine-containing transition-metal complexes, in pure, impure bulk and supported forms.
