A new tridentate ligand (H3L) was prepared from the reaction of 6-formyl-2-(hydroxymethyl)-4-tert-butylphenol and 2-amino-4-nitrophenol. The ligand H3L and acetylacetone were treated with Er (NO3)(3)center dot 5H(2)O, which resulted in the formation of a pentanuclear coordination cluster [Er-5(LH)(4)(acac)(4)(mu(3)-O)(mu(3)-OH)(H2O)(2)](.)5H(2)O (1) (acac = acetylacetonate). Five Er (III) ions are arranged in a nonlinear fashion in 1. Complex 1 was utilized as a catalyst towards the selective synthesis of 1,2-disubstituted benzimidazole derivatives involving o-phenylenediamine and different aldehydes. Yields of 1,2-disubstituted benzimidazole derivatives were in the range of 66%-91%. This study demonstrates the first-ever approach to employ a homo- and pentanuclear lanthanide coordination cluster for catalyzing the synthesis of 1,2-disubstituted benzimidazoles.

Herein, we report the development of a tailored cobalt catalyst system of Cp*Co(III)(LX) toward intramolecular C-H nitrene insertion of azidoformates to afford cyclic carbamates. The cobalt complexes were easy to prepare and bench-stable, thus offering a convenient reaction protocol. The catalytic reactivity was significantly improved by the electronic tuning of the bidentate LX ligands, and the observed regioselectivity was rationalized by the conformational analysis and DFT calculations of the transition states. The superior performance of the newly developed cobalt catalyst system could be broadly applied to both C(sp(2))-H and C(sp(3))-H carbamation reactions under mild conditions.

The development of a redesigned and improved second-generation synthesis of the Nav1.7 inhibitor GDC-0276 based on experience gained from a fit-for-purpose first-generation synthesis will be described. The first-generation synthesis proceeded via a regioselective SNAr reaction on the advanced starting material t-butyl 5-chloro-2,4-difluorobenzoate with 1-adamantanemethanol. In the newly developed second-generation synthesis, the much improved regioselective SNAr reaction was performed on the readily available starting material 1-chloro-2,4-difluorobenzene, followed by installation of the carboxylate group by electrophilic aromatic bromination and a palladium-catalyzed alkoxycarbonylation. A subsequent Suzuki-Miyaura cross-coupling reaction was then telescoped directly into a phase-transfer-catalyzed ester hydrolysis. Amidation of the resulting acid intermediate with 1-azetidine sulfamide in turn provided GDC-0276 in high overall yield and purity on a 100 kg scale.

Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels. However, no routine method currently exists for the reliable determination of these groups in hydrotreated bio-oils (HBOs). In this paper, we analyzed 140 different pure oxygenates as model compounds using the bromine number method (ASTM D1159) observing that most compounds present in HBOs react with one equivalent of bromine. The determination of phenols using bromine number method in crude biooil is complicated especially by the presence of guaiacols and syringols that react with more than one equivalent of bromine and, thus, the obtained result is significantly overestimated. Further we optimized the chromatographic separation of hydrocarbons from HBOs for the selective determination of olefins content. As no other reactive compounds under the conditions of the method, besides phenols and olefins, were observed in HBOs, the difference between HBO bromine number (before hydrocarbons separation) and olefins content correspond to the total amount of phenols. The method was finally applied to 11 HBOs with different content of oxygen, providing a good correlation between phenols and oxygen content.

Recommanded Product: 100-51-6. Recently I am researching about DEFECTIVE UIO-66; STATE, Saw an article supported by the Ministere de l’Enseignement Superieur, de la Recherche et de l’Innovation. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Gairola, P; Millot, Y; Krafft, JM; Averseng, F; Launay, F; Massiani, P; Jolivalt, C; Reboul, J. The CAS is 100-51-6.

A series of zirconium-terephthalate UiO-66 metal-organic frameworks (MOFs) containing partially uncoordinated zirconium sites (Zr-UC) were synthesized, finely characterized by complementary physico-chemical techniques, and employed to catalyze the oxidative dehydrogenation of alcohols in the presence oftert-butyl hydroperoxide (TBHP). These sites were two-fold: bulk Zr(UC)sites created by reducing the content of terephthalate linkers within the framework and intrinsic Zr(UC)sites existing on the external surface of undefective UiO-66 crystals. The activity of both sites was evidenced by the linear dependency taking place between the activity and either the missing linkers or external surface area. Combining in one UiO-66 crystal a high density of Zr(UC)sites within the bulk and a high external surface area enabled the performances of the catalysts in alcohol dehydrogenation to be maximized, making the oxidation of benzyl alcohol over 90% at mild temperature (T= 40 degrees C) after 2 h of reaction possible. More challenging secondary alcohols were also oxidized. The formation of Lewis acid sites at the inorganic nodes was monitored by FTIR spectroscopy of adsorbed CO. The presence of bulk and/or external Zr(UC)sites was further disclosed by the observation on hydrated samples of solid-state(1)H NMR signals, corresponding to the protons of terminal mu(1)-OH moieties capping the Zr(UC)sites. Interestingly, two distinct NMR signals corresponding to the terminal mu(1)-OH moieties of bulk and surface Zr(UC)sites were identified. Finally, a mechanism of alcohol dehydrogenation using TBHP was proposed relying on the concomitant coordination of benzyl alcohol and TBHP onto the two adjacent Zr(UC)sites at the zirconium cornerstones.

Background The nano-sized particles enhance the exposed surface area of the active part of the catalyst, thereby increasing the contact between precursors and catalyst considerably. In this study, nano-SiO2/1,5-diazabicyclo[4.3.0]non-5-en was synthesized, characterized and used as a heterogeneous nanocatalyst for the synthesis of tetrahydrobenzo[b]pyran derivatives. Fourier Transform Infrared Spectroscopy, Field Emission Scanning Electron Microscopy, Brunauer-Emmett-Teller plot, Energy Dispersive X-ray Spectroscopy and Thermo Gravimetric Analysis were used to discern nano-SiO2/1,5-diazabicyclo[4.3.0]non-5-en. Results Tetrahydrobenzo[b]pyrans were synthesized by using nano-SiO2/1,5-diazabicyclo[4.3.0]non-5-en via one-pot three-component condensation of malononitrile, aldehydes and dimedone in H2O/EtOH at 60 degrees C. The results indicate that tetrahydrobenzo[b]pyrans were synthesized in good to high yields and short reaction times. Conclusions The fundamental privileges of this method are short reaction time, plain procedure, recyclability of catalyst and high yields of products.

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp(2))-H diphosphorylation. This reaction represents a rare example of realizing the challenging double C-P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

Bimetallic silver and copper incorporated mesoporous MCM-48 (Ag/CuO/MCM-48) was synthesized by simple wet-impregnation method. The knowledge about its structural properties was gathered by means of Fourier transform-infrared, energy-dispersive X-ray, X-ray diffraction, field emission-scanning electron microscopy, transmission electron microscopy and Brunauer-Emmett-Teller analyses. The catalytic activity of Ag/CuO/MCM-48 was examined in the one-pot three-component reaction of 3-(1-methyl-1H-pyrrol-2-yl)-3-oxopropanenitrile, malononitrile and various aromatic aldehydes leading to novel pyran-pyrrole hybrid derivatives in reduced reaction times (5-10 min) and excellent yields (88-97%). Application of Ag/CuO/MCM-48 as a potent heterogeneous catalyst with good reusability up to five times, use of ethanol as an eco-compatible medium and chromatography-free work-up are some crucial green aspects of this procedure.
