Based on the agrochemical structure of anthranilic diamides, fourteen novel N-substittitedphenyl-2-pyrazolylnicotinamides were conveniently synthesized with 2-chloro-3-cyanopyridine and 4-bromopyrazole or 3,5-dimethylpyrazole as starting materials, via an acyl transposing design strategy. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay tests indicated that most of these compounds exhibited obvious insecticidal activity at the test concentration of 200 mg/L, among which N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)nicotinamide (II) possessed a 70% mortality rate against Mythimna separata Walker: some of the compounds displayed favorable fungicidal activities at 50 mg/L towards Physalospora piricola and Alternaria solani Sorauer, especially 2-(4-bromo-1H-pyrazol-1-yl)-N-(2-(cyclopropylcarbamoyl)-4-iodo-6-methylphenyl)nicotinamide (If) and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)nicotinamide (Ih) against Physalospora piricola, and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(propylcarbamoyl)phenyl)nicotinamide (Id) against Alternaria solani Sorauer had growth inhibitory rates of 62.9%, 54.3% and 54.5%, respectively. These research results provide important reference for the further study of novel 2-pyrazolylnicotinamide derivatives.

In this work, three novel nonmetallic pentazole salts (6-8) based on furazan or 4-nitropyrazole were synthesized. Some coplanar groups were introduced into the compounds to improve the planarity of the crystal packing. 4-Amino-1,2,5-oxadiazole-3-carbohydrazonamide pentazolate (6), 5-(4-amino-1,2,5-oxadiazol-3-yl)-4H-1,2,4-triazole-3,4-diamine pentazolate (7), and 5,5′-(4-nitro-1H-pyrazole-3,5- diyl)-bis(4H-1,2,4-triazole-3,4-diamine) pentazolate (8) all show more stable pi-pi stacking and exhibit superior thermal stability (110.5-116.4 degrees C) than most other reported nonmetallic pentazole salts (T-onset: 80-110 degrees C), and compound 8 has the highest crystal density (1.722 g.cm(-3)/173 K) of nonmetallic pentazole salts to date. All salts have been thoroughly characterized by NMR (H-1 and C-13) spectroscopy, infrared (IR), Roman (RA), and elemental analysis. The decomposition temperature of all salts displays more than 110 degrees C, which is measured by differential scanning calorimetry (DSC). These compounds all shows low sensitivity (IS > 35 J, FS > 360 N) measured by standard BAM methods. Glycidyl azide polymer (GAP) based propellant formula with the addition of salt 6 or 7 shows a higher specific impulse (6, I-sp = 262.1 s; 7, I-sp = 263.9 s) than that of RDX (I-sp = 259.0 s). This study can provide a new crystal engineering way for the synthesis of pentazole salt to solve the problem of low density and poor stability.

Two novel space craft-like octanuclear Co(II)-silsesquioxane nanocages, {Co-8[(MeSiO2)(4)](2)(dmpz)(8)} (SD/Co8a) and {Co-8[(PhSiO2)(4)](2)(dmpz)(8)} (SD/Co8b) (SD = SunDi; Hdmpz = 3,5-dimethylpyrazole), have been constructed from two similar multidentate silsesquioxane ligands assisted with a pyrazole ligand. The Cob skeleton consists of eight tetrahedral Co(II) ions arranged in a ring and is further capped by two (MeSiO2)(4) ligands up and down. The auxiliary dmpz(-) ligands seal the ring finally. Electrospray ionization mass spectrometry revealed SD/Co8a and SD/Co8b are highly stable in CH2Cl2. Magnetic analysis implies that SD/Co8a announces antiferromagnetic interactions between Co(II) ions. Moreover, both of them display good homogeneous catalytic activity for hydroboration of ketones in the presence of pinacolborane under mild conditions.

Acid-sensing ion channels (ASICs) are a family of ion channels permeable to cations and largely responsible for the onset of acid-evoked ion currents both in neurons and in different types of cancer cells, thus representing a potential target for drug discovery. Owing to the limited attention ASIC2 has received so far, an exploratory program was initiated to identify ASIC2 inhibitors using diminazene, a known pan-ASIC inhibitor, as a chemical starting point for structural elaboration. The performed exploration enabled the identification of a novel series of ASIC2 inhibitors. In particular, compound 2u is a brain penetrant ASIC2 inhibitor endowed with an optimal pharmacokinetic profile. This compound may represent a useful tool to validate in animal models in vivo the role of ASIC2 in different neurodegenerative central nervous system pathologies.

An intermolecular hydroalkylative dearomatization of naphthalenes with commercially available alpha-amino acids is achieved via visible-light photoredox catalysis. With an organic photocatalyst, a series of multi-substituted 1,2-dihydronaphthalenes are obtained in good-to-excellent yields. Intriguingly, by tuning the substituents at the C2 position of naphthalenes, formal dearomative [3+2] cycloadditions occur exclusively via a hydroalkylative dearomatization-cyclization sequence. This overall redox-neutral method features mild reaction conditions, good tolerance of functionalities, and operational simplicity. Diverse downstream elaborations of the products are demonstrated. Preliminary mechanistic studies suggest the involvement of a radical-radical coupling pathway.

Using TiOⁱPr4 with a pyrazole ligand for one-pot LA polymerization improved catalytic activity compared with using TiOⁱPr4 only. At 60 degrees C, TiOⁱPr4 with ^furPz exhibited a higher catalytic activity (approximately 3-fold) than TiOⁱPr4. At room temperature, TiOⁱPr4 with ^BuPz exhibited a higher catalytic activity (approximately 17-fold) than TiOⁱPr4. High molecular mass PLA (MnGPC = 51 100, and D = 1.10) could be produced by using TiOⁱPr4 with ^furPz in melt polymerization ([TiOⁱPr4] : [^furPz] = 1000 : 1 : 1 at 100 degrees C, 240 min). The crystal structure of ^MePz2Ti2OⁱPr7 revealed the cooperative activation between two Ti atoms during LA polymerization.

Nucleophilic aromatic substitution (SNAr) is a classical reaction with well-known reactivity toward electron-poor fluoroarenes. However, electron-neutral and electron-rich fluoro(hetero)arenes are considerably underrepresented. Herein, we present a method for the nucleophilic defluorination of unactivated fluoroarenes enabled by cation radical-accelerated nucleophilic aromatic substitution. The use of organic photoredox catalysis renders this method operationally simple under mild conditions and is amenable to various nucleophile classes, including azoles, amines, and carboxylic acids. Select fluorinated heterocycles can be functionalized using this method. In addition, the late-stage functionalization of pharmaceuticals is also presented. Computational studies demonstrate that the site selectivity of the reaction is dictated by arene electronics.

Four new derivatives of the versatile polyfunctional ligands 3-(pyrazol-1-yl)propanamide (1, = PPA) and 3-(3,5-dimethylpyrazol-1-yl)-propanamide (2, = Me(2)PPA) have been prepared, in which one of the amide hydrogens on 1 and 2 is formally replaced by alkyl residues. X-Ray diffraction studies revealed that, in contrast to 1 and 2, the N-isopropyl substituted derivatives 3 and 4 form supramolecular hydrogen-bonded chains rather than two-dimensional arrays, and the N-(2-methyl-4-oxypentan-2-yl) (=MOP) substituted compounds 5 and 6 exist as cyclic dimers in the solid state. Reactions of PdCl2(COD) (COD = 1,5-cyclooctadiene) with 2 equiv. of the corresponding ligands 1-6 in all cases afforded trans-PdCl2(L)(2) complexes (7-12). X-ray crystal structure determinations of 8, and 10-12 revealed kappa N-monodentate coordination of the PPA-type ligands. (C) 2019 Elsevier Ltd. All rights reserved.

A new convenient and versatile halogenating system (R(4)NHal/NOHSO4), giving straightforward and general access to halogenated 3,5-diaryl- and alkylarylisoxazoles, pyrazoles and electron-rich benzenes from the corresponding scaffolds, is suggested. The method provides excellent regioselectivity, scalability to the gram scale, and a broad scope for both aromatics and halogens. A three-step, one-pot reaction protocol was developed, and a series of 3,5-diaryl-4-haloisoxazoles has been efficiently synthesized from 1,2-diarylcyclopropanes under suggested nitrosating-halogenating conditions.
