In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.

An unprecedented approach for assembling a broad range of 1,2-diarylethane derivatives with fluorine-containing fully substituted carbon centers was developed. The protocol features straightforward operation, proceeds under metal-free condition, and accommodates a large variety of synthetically useful functionalities. The critical aspect to the success of this novel transformation lies in using aryldiazonium salts as both aryl radical progenitor and also as single electron acceptor which elegantly enables a radical-polar crossover manifold.

A method for the semi-reduction of alkynoic acids through an alpha-borylation and subsequent protodeborylation mechanism has been developed. The transition metal-free protocol is achieved through the activation of bis(pinacolato)diboron by an in situ generated carboxylate moiety yielding aryl acrylic acids. Our studies demonstrate an unprecedented dual role for the carboxylate anion that involves the activation of the diboron reagent and a directing effect in the alpha-borylation. (C) 2019 Elsevier Ltd.

The Name is Dimethyl 5-aminoisophthalate. Through research, I have a further understanding and discovery of 99-27-4.

Three novel flexible sulfur-containing MOF materials named Co-URJC-5, Cu-URJC-6 and Zn-URJC-7, based on the 5,5′-thiodiisophthalic acid linker have been synthesized through solvothermal methods and characterized by different physicochemical techniques. Hydrogen adsorption analysis at room temperature reveals that these compounds display a gate-opening type adsorption mechanism at low pressures, attributed to the flexible nature of the H4TBTC ligand. This behavior is even more noticeable for Cu-URJC-6, since the layer arrangement by p-p stacking interactions between the aromatic layers could contribute to the flexibility of the structure. These results can be considered as a representative example to elucidate how MOF structures are built using flexible ligands and more significantly as a promising route for designing materials with selective gas sorption properties.

HPLC of Formula: C10H10O2. I found the field of Chemistry very interesting. Saw the article Scope and Mechanism of the Ruthenium-Catalyzed Dehydrative C-H Coupling of Phenols with alpha,beta-Unsaturated Carbonyl Compounds: Expedient Synthesis of Chromene and Benzoxacyclic Derivatives published in 2019.0, Reprint Addresses Yi, CS (corresponding author), Marquette Univ, Dept Chem, Milwaukee, WI 53233 USA.. The CAS is 103-26-4. Through research, I have a further understanding and discovery of Methyl 3-phenyl-2-propenoate.

Chromene and benzoxacyclic derivatives were efficiently synthesized from the ruthenium-catalyzed dehydrative C-H coupling reaction of phenols with alpha,beta-unsaturated carbonyl compounds. The cationic ruthenium-hydride complex was found to be an effective catalyst for the coupling and annulation of phenols with enals to form chromene products. The coupling of phenols with linear enones afforded 2,4-disubstituted chromene derivatives, whereas the analogous coupling with cyclic enones yielded 9-hydroxybenzoxazole products. The reaction of 3,5-dimethoxyphenol with PhCH=CHCDO resulted in the chromene product with a significant H/D exchange to both benzylic and vinyl positions. The most significant carbon isotope effect from the coupling of 3,5-dimethoxyphenol with 4-methoxycinnamaldehyde was observed on the a-olefinic carbon of the chromene product (C(2) = 1.067). A Hammett plot from the coupling of 3,5-dimethoxyphenol with para-substituted p-X-C6H4CH=CHCHO displayed a linear correlation, with a strong promotional effect by an electron -withdrawing group (rho = +1.5; X = OCH3, CH3, H, F, Cl). Several biologically active chromenone derivatives were synthesized by using the catalytic coupling method. The catalytic method provides an expedient synthetic protocol for the coupling of phenols with alpha,beta-unsaturated carbonyl compounds without employing reactive reagents or forming any wasteful byproducts.

A pyridine-based amide functionalized tetracarboxylic acid, 5,5 ‘-(pyridine-2, 6-dicarbonyl)bis(azanediyl)}diisophthalic acid (H4L), was synthesized and its coordination chemistry toward zinc(II) and cadmium(II) ions was studied. The reactions of H4L with Zn(NO3)(2).6H(2)O and Cd(NO3)(2).4H(2)O led to its full or partial deprotonation, respectively, and the formation of the 2D coordination polymers [Zn-2(L)(H2O)(4)](n).4n(H2O) (1) and [Cd-3(HL)(2)(DMF)(4)](n).4n(DMF) (2) (DMF = N,N’-dimethylformamide), respectively. They were characterized by elemental analysis, FT-IR, photoluminescence, thermogravimetry, and single-crystal and powder X-ray diffraction. In 1, the L4- ligand is planar with every carboxylate anion binding a Zn(II) cation and giving rise to a 2D grid with the metals with tetrahedral environments. In 2, the combination of bridging HL3- and dimethylformamide to form trinuclear Cd(II) clusters engenders secondary building block units and generates a layer-type 2D network with the metals with octahedral and pentagonal bipyramid coordination geometries. The topological analyses of 1 and 2 reveal 2,4-connected and 3,6-connected binodal nets, respectively. On account of the presence of Lewis acid (Zn or Cd centers) as well as basic (uncoordinated pyridine and amide groups) sites, 1 and (to a much lower extent) 2 effectively catalyze the one-pot cascade deacetalization-Knoevenagel condensation reactions under quite mild conditions. They act as heterogeneous catalysts, being easy to recover and recycle without losing activity.

As a novel Sanger-type reagent, 2-fluoro-5-nitrophenyldiazonium tetrafluoroborate enabled the versatile functionalization of primary and secondary aliphatic alcohols. Based on a mild nucleophilic aromatic substitution of the fluorine atom under unprecedented, base-free conditions, the diazonium unit on the aromatic core of the resulting aryl-alkyl ether could be employed for such diverse transformations as radical C-H activation and cyclization, as well as palladium catalyzed cross-coupling reactions.

Background Atrial fibrillation (AF) worsens cardiovascular (CV) outcomes of heart failure (HF) and vice versa. The impact of rate or rhythm control strategies on HF progression and survival remains unclear. Methods We examined the risk of HF progression in AF patients (pts) with a prior HF event and minimal or no HF burden (NYHA class 0 or 1). They were stratified into HF with a preserved left ventricular ejection fraction (>= 40%, pEF) or reduced EF (< 40%, rEF). HF subgroups from the Rate and Rhythm arm were compared for the primary outcome of worsening HF or death (WHFD), total mortality, cardiovascular mortality, and cardiovascular hospitalizations. Results Four hundred ninety-two AF pts (HFpEF = 349, HFrEF = 143) were analyzed. Baseline characteristics were generally comparable in the Rate and Rhythm arms of the two subgroups. Over a median follow-up of 4 years, HF recurred and worsened in 66.6% and 41.2% of pts by >= 1 and >= 2 NYHA classes, respectively. HF progression by even 1 NYHA class increased the mortality risk in HFpEF (hazard ratio (HR) 2.06; 95% confidence intervals (CI) 1.25-3.4; p = 0.004) and HFrEF (HR 1.9; 95% CI 0.99-3.66; p = 0.054). Cardiovascular hospitalization (CVH) increased in HFpEF (HR 3.67; 95% CI 2.56, 5.25; p < 0.0001) and HFrEF (HR 2.8; 95% CI 1.53-5.14; p = 0.0009). HF progression by 2 or more NYHA classes or death was significantly worse in pts with HFrEF with the Rate control strategy compared with the Rhythm control (HR 1.62; 95% CI 1.03-2.53; p = 0.036) but similar in pts with HFpEF (HR 0.88; 95% CI 0.64-1.21; p = 0.440).The time to first AF recurrence was longer in the Rhythm arms of both HF subgroups as compared with Rate (Figure, p < 0.05). Conclusions (1) HF progression in AF pts with a prior HF event confers significant mortality and CVH risk in both HFrEF and HFpEF populations. (2) HF progression is more pronounced with a Rate control strategy in AF pts with HFrEF, but is comparable to Rhythm control in AF pts with HFpEF. (3) A Rhythm control strategy may be desirable to reduce HF progression in pts with HFrEF and AF. Prospective clinical trials appear warranted to examine HF progression by treatment strategy in HFpEF and HFrEF populations with AF. Recommanded Product: 103-25-3.
