Wang, Shengdong; Huang, Haiyun; Roisnel, Thierry; Bruneau, Christian; Fischmeister, Cedric published the artcile< Base-Free Dehydrogenation of Aqueous and Neat Formic Acid with Iridium(III) Cp*(dipyridylamine) Catalysts>, Safety of 2-Bromo-N,N-dimethylpyridin-4-amine, the main research area is preparation crystal structure iridium cyclopentadiynyl dipyridylamine complex; cyclic voltammetry iridium cyclopentadiynyl dipyridylamine complex; Dehydrogenation formic acid iridium cyclopentadiynyl dipyridylamine complex catalyst; N ligands; dehydrogenation; energy conversion; hydrogen; iridium.

The selective dehydrogenation of formic acid by iridium(III) Cp*(dipyridylamine) catalysts is reported. The electron-enriched catalyst [IrIIICp*{(4-dimethylaminopyridin-2-yl-κN)(pyridin-2′-yl-κN)amine}(OSO3)] gave the best performances enabling the base free dehydrogenation of aqueous and neat formic acid. In both cases the reaction was selective with no carbon monoxide detectable. The IrIII complex demonstrated latent behavior, which may be of practical utility. Exptl. results suggest an outer-sphere interaction with the ligand.

Gu, Jin-Zhong’s team published research in Inorganic Chemistry Frontiers in 2021 | 366-18-7

Inorganic Chemistry Frontiers published new progress about Benzaldehydes Role: RCT (Reactant), RACT (Reactant or Reagent). 366-18-7 belongs to class pyridine-derivatives, and the molecular formula is C10H8N2, Safety of 2,2′-Bipyridine.

Gu, Jin-Zhong; Wan, Shi-Mao; Dou, Wei; Kirillova, Marina V.; Kirillov, Alexander M. published the artcile< Coordination polymers from an unexplored biphenyl-tricarboxylate linker: hydrothermal synthesis, structural traits and catalytic cyanosilylation>, Safety of 2,2′-Bipyridine, the main research area is coordination polymer biphenyl tricarboxylate linker hydrothermal synthesis catalytic cyanosilylation.

A novel biphenyl-tricarboxylic acid, 3,2′,4′-biphenyl-tricarboxylic acid (H3bta), was used as a versatile linker for preparing a new series of nickel(II), zinc(II), and cadmium(II) coordination polymers (CPs) and complexes, formulated as {[Cd(μ-Hbta)(2,2′-bipy)(H2O)]·3H2O}n (1), {[Ni(μ-Hbta)(4,4′-bipy)(H2O)3]·H2O}n (2), [M2(μ-Hbta)2(4,4′-bipy)2(H2O)2]·2H2O (M = Zn (3) and Cd (4)), {[Cd2(μ4-bta)(μ-Cl)(phen)2]·2H2O}n (5). {[Zn2(μ3-bta)(2,2′-bipy)2(H2O)3][Zn(μ-bta)(2,2′-bipy)(H2O)]·3H2O} (6), {[Cd3(μ4-bta)2(2,2′-bipy)3]·4H2O}n (7), {[Zn3(μ3-bta)2(H2biim)2(μ-H2biim)(H2O)2]·2H2O}n (8), and [Zn3(μ6-bta)2(py)2]n (9). These coordination compounds were hydrothermally assembled from the metal(II) chlorides, H3bta as a principal building block and N-donor ancillary ligands as crystallization mediators (i.e., 2,2′-bipyridine, 2,2′-bipy; 4,4′-bipyridine, 4,4′-bipy; 1,10-phenanthroline, phen; 2,2′-biimidazole, H2biim; or pyridine, py). All the synthesized products 1-9 were characterized by standard solid-state methods including elemental anal., IR spectroscopy, thermogravimetric anal. (TGA), powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. The structures of 1-9 range from 0D dimers (3 and 4) to 1D coordination polymers (1, 2, 5, and 6) and 2D metal-organic layers (7-9). Such a diversity of structures is explained by the differences in metal(II) centers, deprotonation levels of H3bta, and crystallization mediators. From a topol. perspective, the obtained structures include 2C1 chains (in 1, 2, and 6), pcu H-bonded nets (in 3 and 4), SP 1-periodic nets (in 5), and 4,5L51 (in 7) and hcb (in 8) layers. For compounds 1-9, luminescence properties were also evaluated. Besides, the catalytic behavior of the obtained products was screened in the cyanosilylation of benzaldehydes with trimethylsilyl cyanide to give cyanohydrin products under mild conditions, including an optimization of various reaction parameters and an investigation of the substrate scope. Among the tested compounds, 3 acts as the most efficient and recyclable heterogeneous catalyst with up to 96% product yields. By presenting the unique examples of coordination compounds derived from H3bta, this study introduces its use as a new tricarboxylate linker for assembling functional coordination polymers and metal complexes.

Di Fabio, Romano; Arban, Roberto; Bernasconi, Giovanni; Braggio, Simone; Blaney, Frank E.; Capelli, Anna M.; Castiglioni, Emiliano; Donati, Daniele; Fazzolari, Elettra; Ratti, Emiliangelo; Feriani, Aldo; Contini, Stefania; Gentile, Gabriella; Ghirlanda, Damiano; Sabbatini, Fabio M.; Andreotti, Daniele; Spada, Simone; Marchioro, Carla; Worby, Angela; St-Denis, Yves published the artcile< Dihydropyrrole[2,3-d]pyridine Derivatives as Novel Corticotropin-Releasing Factor-1 Antagonists: Mapping of the Receptor Binding Pocket by in Silico Docking Studies>, COA of Formula: C9H9Cl2NO2, the main research area is pyrrolo pyridine preparation CRF1 antagonist antidepressant SAR.

In an effort to discover novel CRF-1 receptor antagonists exhibiting improved physicochem. properties, a dihydropirrole[2,3]pyridine scaffold was designed and explored in terms of the SAR of the substitution at the pendent Ph ring and the nature of the heterocyclic moieties present in the upper region of the mol. Selective and potent compounds have been discovered endowed with reduced ClogP with respect to compounds known in the literature. Of particular relevance was the finding that the in vitro affinity of the series was maintained by reducing the overall lipophilicity. The results achieved by this exploration enabled the formulation of a novel hypothesis on the nature of the receptor binding pocket of this class of CRF-1 receptor antagonists, making use of in silico docking studies of the putative nonpeptidic antagonist binding site set up in house by homol. modeling techniques.

Journal of Medicinal Chemistry published new progress about Blood-brain barrier (penetration). 86129-63-7 belongs to class pyridine-derivatives, and the molecular formula is C9H9Cl2NO2, Application of C9H9Cl2NO2.

Dyck, Brian; Grigoriadis, Dimitri E.; Gross, Raymond S.; Guo, Zhiqiang; Marinkovic, Dragan; McCarthy, James R.; Moorjani, Manisha; Regan, Collin F.; Saunders, John; Schwaebe, Michael K.; Szabo, Tomas; Williams, John P.; Zhang, Xiaohu; Bozigian, Haig; Chen, Ta Kung published the artcile< Potent, Orally Active Corticotropin-Releasing Factor Receptor-1 Antagonists Containing a Tricyclic Pyrrolopyridine or Pyrazolopyridine Core>, Application of C9H9Cl2NO2, the main research area is oral CRF1 receptor antagonist tricyclic pyrrolopyridine pyrazolopyridine core preparation.

Two new classes of tricyclic-based corticotropin-releasing factor (CRF1) receptor-1 antagonists were designed by constraining known 1H-pyrrolo[2,3-b]pyridine and 1H-pyrazolo[3,4-b]pyridine ligands. Pyrrole- and pyrazole-based mols. 19g and 22a, resp., were discovered that potently bind the recombinant CRF1 receptor (Ki = 3.5, 2.9 nM) and inhibit adrenocorticotropic hormone (ACTH) release from rat pituitary cell culture (IC50 = 14, 6.8 nM). These compounds show good oral bioavailability (F = 24%, 7.0%) and serum half-lives in rats (t1/2 = 6.3, 12 h) and penetrate the rat brain ([brain]/[plasma] = 0.27, 0.52) but tend toward large volumes of distribution (VD = 38, 44 L kg-1) and rapid clearances (CL = 70, 43 mL min-1 kg-1). When given orally, both the pyrazole and the pyrrole leads dose-dependently inhibit stress-induced ACTH release in vivo. ACTH reductions of 84-86% were observed for 30 mg kg-1 doses.
