Cobalt-Catalyzed Enantioselective Directed C-H Alkylation of Indole with Styrenes

A cobalt-chiral phosphoramidite catalyst promotes enantioselective imine-directed C2-alkylation of Boc-protected indoles with styrenes. The reaction affords 1,1-diarylethane products in moderate to good yields with good enantioselectivities under mild conditions. A deuterium-labeling experiment suggests that the enantioselectivity is controlled by both the styrene insertion and the C-C reductive elimination steps. (Chemical Equation Presented).

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: (S)-[1,1′-Binaphthalene]-2,2′-diol, you can also check out more blogs about18531-99-2

Structural studies of thermal- and light- induced transitions in iron(II) spin-crossover complexes

Since the spin-crossover (SCO) effect was first discovered, considerable efforts have been made to study compounds that exhibit this phenomenon. Herein we present a selection of our most exciting results from structural studies carried out on some of the fascinating iron(II) SCO compounds we have investigated over the past few years. We discuss a range of compounds from mononuclear to bimetallic polymeric complexes.

THERMODIFFUSION EN SOLUTION AQUEUSE: COMPARAISON ENTRE LES CHLORURES ALCALINS ET LES BROMURES DE TETRAALKYLAMMONIUM SYMETRIQUES

Two different apparatus were used to measure Soret coefficients (sT), reduced heats of transport (Q) and isothermal diffusion coefficients of aqueous solutions of tetramethyl, ethyl, propyl and butylammonium bromide.The first one is classically based on a beam deflection.It allows the measure of sT and D between 0.2 and 2 molar or about.The second one is based on the solution separation into two partitions by means of a thin stell strip.It allows the measure in the field of low concentrations.Our results show that the behaviours of sT and Q are clearly different for the larger cations (Pr4N+ and Bu4N+) and for the alkalines.It is established that the thermal diffusion, like other physico-chemical properties, allows to cut the set of ions in two classes.

Luminescent Electropolymerizable Ruthenium Complexes and Corresponding Conducting Metallopolymers

Tris(2,2?-bipyridyl)ruthenium(II) dichloride [Ru(bpy)3Cl2] and analogous complexes have been studied extensively in the literature due to their luminescent and photochemical properties as well as their excited-state lifetimes. Conducting polymers with similar ruthenium groups have also been investigated for various applications. In this study, syntheses of four ruthenium complexes with a polymerizable tridentate ligand, bis[4-[2-(3,4-diethylenedioxy)thiophene]pyrazol-1-yl]pyridine (EDOT2NNN), and with bidentate ligands, two of which were anionic (hfac: 1,1,1,5,5,5-hexafluoro-2,4-pentanedione; dbm: dibenzoylmethane) and two of which were neutral (bpy: 2,2?-bipyridyl; phen: 1,10-phenanthroline), were achieved for potential OLED/PLED applications. Saturated CH2Cl2 solutions of monomers were oxidatively and electrochemically polymerized, and the scan rate dependences of the polymers were measured. UV-vis spectroscopic characterizations of the complexes and the EDOT-functionalized ligand were obtained. [Ru(EDOT2NNN)(phen)(Cl)](PF6) was electropolymerized on an ITO (indium tin oxide)-coated glass surface to obtain the solid-state absorption spectrum of the corresponding polymer. Photophysical data for each complex, i.e., excitation and emission spectra at 77 K and RT, in EtOH/MeOH (4:1) and in 2-MeTHF (dry, air-free, and aerated), quantum yield, and luminescence lifetime have been measured. The radiative and nonradiative decay constants as well as the oxygen quenching rate coefficient for each complex were calculated. [Ru(EDOT2NNN)(phen)(Cl)](PF6), having the highest quantum yield of phosphorescence and the longest lifetime, was electropolymerized on an ITO-coated glass surface to obtain the solid-state excitation and emission spectra of the corresponding polymer. Luminescence studies of the polymer had promising results for photoluminescence.
