Access to multinuclear salen complexes using olefin metathesis

The use of olefin metathesis as a construction tool for multimetallic salen-based structures is described. The approach involves mono- and diallyl-functionalized metallosalen complexes that can be directly coupled by metathesis leading to dimetallic species or mixtures of linear and cyclic oligomers. The metathesis of bis-allyl Ni(salen) complexes has been studied in detail. At high concentration it is possible to selectively obtain di-Ni species rather than heavier oligomers while under dilute conditions cyclic rather than linear oligomers are preferentially obtained. A mono-allyl Zn(salphen) complex was efficiently coupled using metathesis to give the di-Zn(salphen) product, which was subsequently transmetalated with a variety of metals to yield dimetallic salens of potential catalytic interest. Finally, a tetranuclear Zn4 macrocycle was also prepared using buildings blocks obtained by metathesis from commercially available precursors. The methods described herein allow for the facile construction of multi-centered Schiff base complexes of catalytic or supramolecular interest.

Latent catalytic systems for ring-opening metathesis-based thermosets

Synthesis and curing activity of latent ring-opening metathesis polymerization (ROMP)-based catalytic systems are reported using polydicyclopentadiene (pDCPD) as a model system. Differential scanning calorimetry (DSC) is used to monitor the ROMP reactions and to characterize the cured networks. These systems are either slow or completely inactive at ambient temperatures, yet at high temperatures the superior curing activity of other ROMP catalysts are retained. The resulting thermosets show glass transition temperatures from 10 to 25 C higher than when cured with other ROMP catalysts.

Diversity-oriented approach to spirocycles with indole moiety via Fischer indole cyclization, olefin metathesis and Suzuki-Miyaura cross-coupling reactions

A range of aryl substituted spirocycles containing the indole moiety have been assembled through Claisen rearrangement, Fischer indole cyclization, ring-closing metathesis and the Suzuki-Miyaura cross-coupling reactions. Some of these molecules contain either a spirocyclic system or an indeno[1,2-b]indole framework, which is present in diverse bioactive targets. Here, we have used simple and readily available starting materials to generate a library of spirocycles with an indole unit in their structures.

New approaches for the synthesis of erythrinan alkaloids

A concise asymmetric total synthesis of (+)-erysotramidine is described, using chiral base desymmetrisation of a meso-imide, N-acyliminium addition, retro-Diels-Alder cycloaddition and radical cyclisation as the key steps. A related route, starting from a cyclobutene-fused imide, was explored, and established a novel construction of the Erythrina alkaloid skeleton using a key ring-opening/ring-closing metathesis step. Completion of this synthesis was thwarted by problems with the removal of an unwanted vinylic side-chain. Complementary enantiospecific routes to Erythrina systems were explored, starting from (L)-malic acid. Some unexpected observations were made concerning the diastereocontrol in malic acid-derived N-acyliminium ion cyclisations, where changing the protecting group of the alcohol function from acetate to OTIPS resulted in a dramatic change in diastereocontrol. Products from these reactions could be transformed into known intermediates for natural alkaloids, and into (+)-demethoxyerythratidinone itself, by means of radical cyclisations or intramolecular aldol reactions as the key steps.

A Spectroscopic and Computationally Minimal Approach to the Analysis of Charge-Transfer Processes in Conformationally Fluxional Mixed-Valence and Heterobimetallic Complexes

Class II mixed-valence bimetallic complexes {[Cp?(PP)M]C?C?C?N[M?(PP)?Cp?]}2+ (M, M?=Ru, Fe; PP=dppe, (PPh3)2; Cp?=Cp*, Cp) exist as conformational ensembles in fluid solution, with a population of structures ranging from cis- to trans-like geometries. Each conformer gives rise to its own series of low-energy intervalence charge-transfer (IVCT) and local d?d transitions, which overlap in the NIR region, giving complex band envelopes in the NIR absorption spectrum, which prevent any meaningful attempt at analysis of the band shape. However, DFT and time-dependent (TD)DFT calculations with dispersion-corrected global-hybrid (BLYP35-D3) or local hybrid (lh-SsirPW92-D3) functionals on a small number of optimised structures chosen to sample the ground state potential energy hypersurfaces of each of these complexes has proven sufficient to explain the major features of the electronic spectra. Although modest in terms of computational expense, this approach provides a more accurate description of the underlying molecular electronic structure than would be possible through analysis of the IVCT band by using the static point-charge model of Marcus?Hush theory and derivatives, or TDDFT calculations from a single (global) minimum energy geometry.

Process for preparing synthesis gas by autothermal reforming

Disclosed is a process for producing a synthesis gas by an autothermal reforming method including a step of partially oxidizing a carbon-containing organic compound to produce a high temperature mixed gas, and a synthesis producing step of reacting the unreacted carbon-containing organic compound contained in the high temperature mixed gas with carbon dioxide and/or steam, wherein a catalyst having a considerably suppressed carbon deposition activity is used as a catalyst for the synthesis gas producing step. The catalyst is characterized in that the catalyst comprises a carrier formed of a metal oxide, and at least one catalytic metal selected from rhodium, ruthenium, iridium, palladium and platinum and supported on the carrier, in that the catalyst has a specific surface area of 25 m2/g or less, in that metal ion of the carrier metal oxide has electronegativity of 13.0 or less, and in that the amount of the catalytic metal supported is 0.0005-0.1 mole %, in terms of a metal, based on the carrier metal oxide.

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.HPLC of Formula: Cl3Ru, you can also check out more blogs about10049-08-8

On the origins of diastereoselectivity in the conjugate additions of the antipodes of lithium N-benzyl-(N-alpha-methylbenzyl)amide to enantiopure cis- and trans-dioxolane containing alpha,beta-unsaturated esters

“Matching” and “mismatching” effects in the doubly diastereoselective conjugate additions of the antipodes of lithium N-benzyl-(N-alpha-methylbenzyl)amide to enantiopure cis- and trans-dioxolane containing alpha,beta-unsaturated esters have been investigated. High levels of substrate control were established first upon conjugate addition of achiral lithium N-benzyl-N-isopropylamide to both tert-butyl (S,S,E)-4,5-O- isopropylidene-4,5-dihydroxyhex-2-enoate and tert-butyl (4R,5S,E)-4,5-O- isopropylidene-4,5-dihydroxyhex-2-enoate. However, upon conjugate addition of lithium (R)-N-benzyl-(N-alpha-methylbenzyl)amide and lithium (S)-N-benzyl-(N-alpha-methylbenzyl)amide to these substrates, neither reaction pairing reinforced the apparent sense of substrate control. These reactions do not, therefore, conform to the classical doubly diastereoselective “matching” or “mismatching” pattern usually exhibited by this class of reaction. A comparison of these reactions with the previously reported doubly diastereoselective conjugate addition reactions of lithium amide reagents to analogous substrates is also discussed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 301224-40-8, in my other articles.

DNA-binding and cleavage, cytotoxicity properties of Ru(II) complexes with 2-(4?-chloro-phenyl) imidazo[4,5-f][1,10]phenanthroline, ligand and their “light switch” on-off effect

Three new complexes of the type [Ru(phen)2PIP-Cl](1) [Ru(bpy)2PIP-Cl](2) and [Ru(dmp)2PIP-Cl](3) (phen = 1,10-phenanthroline; bpy = 2,2?-bipyridine; dmb = 4,4-dimethyl-2,2?- bipyridine), PIP-Cl = 2-(4?-chloro-phenyl) imidazo[4,5-f][1,10] phenanthroline) were synthesized and characterized by using UV-VIS, IR and 1H-NMR, 13C-NMR spectral methods. Absorption spectroscopy, emission spectroscopy, viscosity measurements and DNA melting techniques were used to investigate the binding of these Ru(II) complexes with calf thymus DNA, and photocleavage studies were used to investigate the binding of these complexes with plasmid DNA. The spectroscopic studies together with viscosity measurements and DNA melting studies supported fact that Ru(II) complexes bind to CT-DNA(calf thymus DNA) by an intercalation mode via PIP-Cl into the base pairs of DNA. Upon irradiation, these novel Ru(II) complexes cleave the plasmid pBR 322 DNA from the supercoiled form I to the open circular form II.

An efficient catalytic system for the hydrogenation of quinolines

A new catalytic system ([Ru(p-cymene)Cl2]2/I2) has been developed for the hydrogenation of quinoline derivatives with high reactivity. For the 2-methyl-quinoline, the hydrogenation reaction can proceed smoothly at an S/C of 20,000/1 with complete conversion. The iodine additive is important for the reactivity.

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
