Abstract:

The synthetic studies include the synthesis of the cyclic siloxydiyne, 3,3,5,5,8,8,10,10-octamethyl-4,9-dioxa-3,5,8,10-tetrasilacyclodeca-1,6- diyne [VI] and its novel iron carbonyl complex. In the preparation of [VI] by HBr promoted condensation of bis (methoxydimethylsilyl) acetylene, a minor product, a cyclic trimer was always formed along with the major product [VI]. No evidence of an equilibrium between the trimerization product and the dimerization product was found. Compound [VI] can react with iron carbonyl reagents to produce a novel binuclear iron complex of trimethylenemethane [VII]

Abstract:

Iron-catalysed carbonyl reduction, nitro reduction, formal hydroamination, and the radical alkenylation of alkyl halides have been developed. A Simple, easy-to-make, air- and moisture-stable iron(III) amine-bis(phenolate) complex catalysed the hydrosilylation of carbonyl compounds efficiently using triethoxysilane as the reducing agent. The reaction tolerated a wide range of substrates to give the corresponding alcohol products in good to excellent yields after hydrolysis of the hydrosilylated products (Scheme A1). Scheme A1.

Abstract:

A detailed mechanistic investigation of the previously reported ruthenium pseudo-dipeptide-catalyzed asymmetric transfer hydrogenation (ATH) of aromatic ketones was performed. It was found that the addition of alkali metals has a large influence on both the reaction rate and the selectivity, and that the rate of the reaction was substantially increased when THF was used as a co-solvent. A novel bimetallic mechanism for the ruthenium pseudo-dipeptide-catalyzed asymmetric reduction of prochiral ketones was proposed. There is a demand for a larger substrate scope in the ATH reaction, and heteroar

Abstract:

In recent decades, magnetorheological elastomer (MRE) has been widely used in engineering applications as vibration absorbers or isolators due to its field-dependent property. Thus, researches on the correlations of the variables and MRE behaviors are increasingly needed. This study aims to characterize and simulate magnetorheological behavior of elastomer filled with carbonyl iron and NdFeB particles under uniaxial tension, compression, and pure shear modes. First, tensile tests were performed for both isotropic and anisotropic magnetorheological elastomer (MRE) with carbonyl iron particle (C

Abstract:

The reactivity and micro-structure of three coals and two cokes used in iron and steel manufacture have been studied by a variety of techniques, including gas sorption analysis, thermal analysis and microscopy. Changes in surface areas and porosities of the coals and cokes during combustion have been determined by a gravimetric nitrogen sorption technique at 77K. The cokes and coals have been studied by thermal analysis under isothermal and dynamic conditions in different gas atmospheres. Rates of reaction have been correlated with surface area changes. Attempts have been made to calculate act

Abstract:

CKD is diagnosed when there’s a decreased kidney function shown by a GFR less than 60 ml / min (established for a reference man with 1.73 m² body surface area), or markers of kidney damage, or both, of at least 3 months duration. The severity of complications increases in parallel with the GFR decline. We focused on three comorbidities extremely common in CKD patients: oxidative stress and inflammation; anemia and dysbiosis. We investigated these CKD comorbidities both with in vitro and in vivo approaches. More in detail, regarding in vivo studies, we measured oxidative stress biomarkers in a

Abstract:

L'océan Austral est caractérisé par l’acronyme anglais (HNLC) signifiant qu’il contient des concentrations en nutriments élevées, mais que la biomasse phytoplanctonique y est faible. Cette situation paradoxale est due à la limitation du phytoplancton par le fer (Fe). L'augmentation de la biomasse phytoplanctonique en réponse à l'apport de Fe et, par conséquent, une plus grande absorption de dioxyde de carbone (CO2), a été démontrée dans plusieurs expériences de fertilisation artificielle et dans des régions naturellement fertilisées de l'océan Austral. Cependant, l'impact de Fe sur les procary

Abstract:

Ce travail de recherche est consacré à la réduction des composés carbonylés tels que les aldéhydes, cétones, imines, esters et acides carboxyliques catalysée par des complexes bien définis du fer. La première partie de ce travail porte sur l'utilisation du système Fe(dppe)₂(H)₂ (1mol %) / NaB(OEt)4 (1mol %) comme catalyseur efficace pour l'hydrosilylation des aldéhydes et cétones avec le PHMS sous activation lumineuse. Dans une seconde partie, une famille de complexes du type [CpFe(CO)₂PR₃]X et CpFe(CO)(X)PR₃ (PR₃ = PPh₃ et PCy₃) a été développée et ces complexes se sont révélés être des catal
