A new approach is suggested herein for the synthesis of pyrazole derivatives by reacting 4-nitrosemicarbazide with acetylacetone. Additional studies were done on the reaction of acetylacetone with semicarbazide and its derivatives (4-aminosemicarbazide, methylsemicarbazide, and dimethylsemicarbazide). The study on the reaction with acetylacetone resulted in monocyclic 3,5-dimethyl-N-nitropyrazole-1-carboxamide, monocyclic 5-hydroxy-3,5-dimethyl-2-pyrazoline, and bicyclic bis(3,5-dimethylpyrazole-1-carbonyl)hydrazine, and conditions for the formation of acetone semicarbazone were identified. The structures of the resultant compounds were validated by physicochemical analytical methods, including X-ray diffraction. The computer-aided screening in the PASS prediction software discovered a high biological activity of the newly obtained compounds.

Three kinds of Ni-II complexes, the singly hydroxo-bridged complex 2, doubly hydroxo-bridged complexes 3a and 3b, and dinuclear Ni complex 4, were readily prepared from reactions of the salt K[(BBN)Bp (R)] {(BBN)Bp (R) = (9-BBN)bis(pyrazolyl)borate} and the NiCl2(PPh3)(2) precursor via B-N bond cleavage process in dichloromethane or toluene. Complex 2 is a rare example of partial hydrolysis of the coordinated pyrazolylborate ligand, while complexes 3a and 3b demonstrate the unreported new form that complete hydrolyses of the coordinated pyrazolylborate ligand produced. Different mechanisms for the formation of complexes 2-4 are proposed.

The removal of methylene blue (MB) from aqueous solution has been investigated using new tunable 1-aryl-2-alkyl-3,5-dimethylpyrazolium hexafluorophosphate salts ([Ph(R)C(R?)pz][PF6], R: -Cl, -Br, -Me, -OMe, R?: -C2H5, or -C4H9) as an extractant and methylene chloride as a diluent. The influence of p-substituent and alkyl chain length on the removal efficiency of MB from aqueous solution was investigated. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up to 99.7 % in a very short time. The salt (4a) used for extraction of MB was recovered and reused for four runs.

Bis(pyrazolyl)alkanes are a prolific class of ligands for catalysis, accessible by the condensation between bis(pyrazolyl)methanones and carbonyls. In this report, we describe a nucleophile-catalyzed innovation on this condensation that avoids the transition metals, high temperatures, reagent excess, and air-sensitive reagents common among the existing protocols. Significantly, this method accommodates sterically hindered and electronically diverse pyrazoles and aldehydes, applicable for systematic ligand optimization. Furthermore, our scope includes azoles and bridging functional groups previously unreported for this reaction, promising for new heteroscorpionate catalysts. We provide the first direct evidence for an elusive reaction intermediate and characterize the most complete mechanism for this condensation.

In this work, we report three deep-blue emitting cationic iridium complexes Ir1-Ir3 with 2′,6′-difluoro-2,3′-bipyridine cyclometalated ligand and pyrazole-type ancillary ligands. Synthesis, crystal structure, photophysical and electrochemical properties of Ir1-Ir3 are studied in detail. Ir1-Ir3 exhibit efficient phosphorescence emissions at 439, 438 and 437 nm with CIE 1931 coordinates of (0.14, 0.12), (0.14, 0.12) and (0.14, 0.13), and luminescence quantum yields of 0.35, 0.27 and 0.50 in CH2Cl2 solutions, respectively, which are among the highest levels of ever reported cationic iridium(III) complexes emitting deep-blue light. High luminescence quantum yields, excellent color purity and short lifetimes demonstrates the great potential of Ir1-Ir3 for lightemitting electrochemical cells (LECs) and solution-processable organic light-emitting diodes (OLEDs) as efficient blue emitters.

As consumers generally desire longer lasting scratch-free coatings, scratch resistance has become one of the most important properties of automotive coatings. Surface scratches that deform a coating but do not break it can recover over time, eventually even becoming invisible to the human eye. This phenomenon arises from elastic plastic behavior and is called self-recover?. This paper mainly focuses on the recovery of scratch deformations. Conventional coatings with low glass transition temperature (Tg) have fast recovery characteristics, like rubbers, but cannot attain sufficient hardness. Therefore, it is difficult to simultaneously improve both scratch recovery characteristics and hardness in conventional coatings such as 2 K urethane coatings consisting of acrylic polyols because both arise from the same causes as the mobility of the main chain of the coating. Herein, we explore the remarkable improvement of scratch recovery characteristics without sacrificing hardness by using a base resin with a siloxane main chain instead of a carbon-carbon main chain such as that of an acrylic polyol. We demonstrate that crosslinked polyorganosilsesquioxane coatings (Si-films) achieve both hardness suitable for automobile coatings and improved scratch recovery characteristics superior to those of conventional coatings (C-films). Si-films demonstrated 20% better elastic recovery index than C-films, and the Si-films recovered about twice as fast as the C-films. Scratch deformations on the Si-films almost disappeared after 15 min, even at room temperature, while C-films were needed over 24 days. Thus, coatings based on a siloxane main chain may offer dramatically improved self-recovery.

An article Study of the solvation process of some pyrazole derivatives in three different solvents by solution calorimetry and IR spectroscopy: Unravelling solute-solvent interactions WOS:000545303600024 published article about ENTHALPIES; VAPORIZATION in [Herrera-Castro, Filiberto; Alfonso Torres, Luis] Ctr Invest & Estudios Avanzados, Dept Quim, Av IPN 2508, Ciudad De Mexico 07360, Mexico in 2020.0, Cited 20.0.

The study of the relationship between intermolecular interactions present in the solvation process and the magnitude of thermodynamic properties is extended from imidazole to pyrazole derivatives. The enthalpies of solution of pyrazole, 3,5-dimethylpyrazole and 3,4,5-trimethylpyrazole were calorimetrically determined in the solvents water, methanol and acetonitrile. The enthalpy of solution values for the three compounds in the three solvents are endothermic and spontaneous with an increase in entropy. As in the case with imidazole derivatives, the formation of a solution of pyrazole derivatives creates liquids that are more structured thermodynamically. The enthalpy of sublimation for 3,4,5-trimethylpyrazole, which is not available in the literature, was determined by the Knudsen effusion method. The combination of these thermodynamic properties has allowed the corresponding enthalpies of solvation to be obtained for the three pyrazole derivatives in the three selected solvents. With the use of the Pierotti equations and the enthalpies of solvation, the enthalpies of cavity formation were calculated along with the corresponding solute-solvent enthalpies of interaction. The infrared spectra and molecular volumes, as estimated through the electronic density, were used to obtain molecular insights into the solvation sensible sites within the studied solute molecules. The discussion of the solvation process and enthalpies of interaction of the pyrazole derivatives is based on the molecular structural features of solutes, specific intermolecular interactions and protic or aprotic nature of the solvents. The use of any empirical parameters in the discussion of the results was avoided. (C) 2020 Elsevier B.V. All rights reserved.

A novel nonanuclear nickel(ii) cluster identified as [Ni-9(OH)(6)(CO3)(2)(ba)(8)(Hdmpz)(6)(DMF)(2)]center dot EtOH center dot 2DMF (SD/Ni9a, Hba = benzoic acid, Hdmpz = 3,5-dimethyl-1H-pyrazole) is successfully constructed from mixed ligands. The single-crystal X-ray diffraction (SCXRD) structural analysis confirms the composition and reveals the drum-like inner core structure surrounded by ba(-)and DMF. Six Hdmpz ligands in their neutral form further sandwich the drum up and down, and is hydrogen bonded with two carbonate anions that are derived from the atmospheric CO2 with the help of Et3N. Electrospray ionization mass spectrometry (ESI-MS) reveals that the SD/Ni9a maintains an intact core in the solution with a slight exchange of outer ligands. Detailed collision-induced dissociation (CID) experiments reveal the collision energy (CE)-promoted ligand loss and exchange between ba(-) and Hdmpz. Furthermore, the magnetic study shows that there is no interaction between the Ni centers at room temperature, whereas the ferromagnetic coupling between the Ni centers is found with an S = 3 spin ground state of the cluster at low temperature. Moreover, the UV-vis spectrum and the photocurrent response measurements show its good optical properties with an indirect bandgap of about 2.35 eV and fast current response upon visible light irradiation.

Direct N-glycosylation between glycals and amides/amines was achieved with exclusive stereoselectivity in moderate to high yields. Various amides, amines, and 3,4-O-carbonate-glycals were tolerated, and unique beta-N-glycosides were obtained. The strategy was based on palladium-catalyzed decarboxylative allylation, and the high 1,4-cis-selectivity was proposed because of the hydrogen bonding effect. Notably, all the synthesized products were subjected to preliminary bioactivity studies, revealing that three compounds were cytotoxic to tumor cells and nontoxic to normal human cells.
