I found the field of Chemistry very interesting. Saw the article Molecular squares, coordination polymers and mononuclear complexes supported by 2,4-dipyrazolyl-6H-1,3,5-triazine and 4,6-dipyrazolylpyrimidine ligands published in 2019.0. Application In Synthesis of 3,5-Dimethyl-1H-pyrazole, Reprint Addresses Halcrow, MA (corresponding author), Univ Leeds, Sch Chem, Woodhouse Lane, Leeds LS2 9JT, W Yorkshire, England.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole

The Fe[BF4](2) complex of 2,4-di(pyrazol-1-yl)-6H-1,3,5-triazine (L-1) is a high-spin molecular square, [{Fe(L-1)}(4)(mu-L-1)(4)][BF4](8), whose crystals also contain the unusual HPzBF(3) (HPz = pyrazole) adduct. Three other 2,4-di(pyrazol-1-yl)-6H-1,3,5-triazine derivatives with different pyrazole substituents (L-2-L-4) are unstable in the presence of first row transition ions, but form mononuclear, polymeric or molecular square complexes with silver(i). Most of these compounds involve bis-bidentate di(pyrazolyl)triazine coordination, which is unusual for that class of ligand, and the molecular squares encapsulate one or two BF4-, ClO4- or SbF6- ions through combinations of anion pi, AgX and/or C-HX (X = O or F) interactions. Treatment of Fe[NCS](2) or Fe[NCSe](2) with 4,6-di(pyrazol-1-yl)-2H-pyrimidine (L-5) or its 2-methyl and 2-amino derivatives (L-6 and L-7) yields mononuclear [Fe(NCE)(2)L-2] and/or the 1D coordination polymers catena-[Fe(NCE)(2)(mu-L)] (E = S or Se, L = L-5-L-7). Alcohol solvates of isomorphous [Fe(NCS)(2)L-2] and [Fe(NCSe)(2)L-2] compounds show different patterns of intermolecular hydrogen bonding, reflecting the acceptor properties of the anion ligands. These iron compounds are all high-spin, although annealing solvated crystals of [Fe(NCSe)(2)(L-5)(2)] affords a new phase exhibiting an abrupt, low-temperature spin transition. Catena-[Fe(H2O)(2)(mu-L-5)][ClO4](2) is a coordination polymer of alternating cis and trans iron centres.

Two novel room-temperature disulfonic acid functionalized ionic liquids derived from 3,5-dimethyl-1H-pyrazole consisting of chloride and trichlorostannate anions, 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium chloride and 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium trichlorostannate, have been synthesized, characterized and evaluated for their catalytic efficiency in the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones by the one-pot, three-components reaction of phthalhydrazide, an aromatic aldehyde and malononitrile or ethyl cyanoacetate under solvent-free conditions. The results have demonstrated high catalytic activity of these novel ionic liquids containing acidic SO3H groups in producing high yields of the desired products in short reaction time. The ionic liquids can be used at least four times without any noticeable decrease in catalytic activity.

In this study, three triazole based azo molecules [3-amino-4-[1H-1,2,4-triazole-3-yldiazenyl]-1H-pyrazole-5-ol (1), 3-[(3,5-dimethyl-1H-pyrazole-4-yl)diazenyl]-1H-1,2,4-triazole (2) and 4-[1H-1,2,4triazole-3yldiazenyl]benzene-1,3-diol (3)] were, synthesized and characterized by using 1H NMR, FTIR, UV-vis and mass spectra. The molecular structure, vibrational spectroscopic data, electronic transition absorption wavelengths, HOMOs and LUMOs analyses, molecular electrostatic potential (MEP) and potential energy surface (PES) diagrams were calculated by using DFT/B3LYP method with 6-311G(d,p) basis set. NMR chemical shift calculations were performed by using the gauge-invariant atomic orbital (GIAO) method. The spectroscopic results obtained from quantum chemical calculations of the 1, 2 and 3 molecules were in good agreement with the experimental data. Antibacterial activities of the 1, 2 and 3 were investigated against four different bacterial cultures. Although 1 molecule did not show very good antibacterial activity, 2 and 3 showed good activity against Staphylococcus aureus at a MIC of 250 and 62.5 mg/mL, respectively. Druglikeness and some of the pharmacokinetic properties of the 1, 2 and 3 were also examined. In addition, molecular docking studies were performed to investigate the antibacterial properties of synthesized compounds by in silico method. For this purpose, beta-ketoacyl-acyl carrier protein (ACP) synthase III (KAS III) and lipoteichoic acid synthase (LtaS) inhibitory properties of 1, 2 and 3 molecules were investigated. Although all of the synthesized compounds showed antibacterial properties according to the results of the molecular docking studies, the best results were obtained by the compound 3 which interacts with both KAS III and LtaS with binding energy of -7.17 and -7.53 kcal/mol, respectively.

Name: 3,5-Dimethyl-1H-pyrazole. I found the field of Science & Technology – Other Topics very interesting. Saw the article Photocatalytic three-component asymmetric sulfonylation via direct C(sp(3))-H functionalization published in 2021.0, Reprint Addresses Gong, L (corresponding author), Xiamen Univ, Coll Chem & Chem Engn, iChEM, Key Lab Chem Biol Fujian Prov, Xiamen, Fujian, Peoples R China..

The direct and selective C(sp(3))-H functionalization of cycloalkanes and alkanes is a highly useful process in organic synthesis owing to the low-cost starting materials, the high step and atom economy. Its application to asymmetric catalysis, however, has been scarcely explored. Herein, we disclose our effort toward this goal by incorporation of dual asymmetric photocatalysis by a chiral nickel catalyst and a commercially available organophotocatalyst with a radical relay strategy through sulfur dioxide insertion. Such design leads to the development of three-component asymmetric sulfonylation involving direct functionalization of cycloalkanes, alkanes, toluene derivatives or ethers. The photochemical reaction of a C(sp(3))-H precursor, a SO2 surrogate and a common alpha,beta-unsaturated carbonyl compound proceeds smoothly under mild conditions, delivering a wide range of biologically interesting alpha-C chiral sulfones with high regio- and enantioselectivity (>50 examples, up to >50:1 rr and 95% ee). This method is applicable to late-stage functionalization of bioactive molecules, and provides an appealing access to enantioenriched compounds starting from the abundant hydrocarbon compounds. The direct and selective C(sp(3))-H functionalization of cycloalkanes and alkanes is useful in organic synthesis but its application to asymmetric catalysis has been less explored. Here, the authors demonstrate the incorporation of a dual asymmetric photocatalyst which leads to the development of asymmetric sulfonylation involving direct functionalization of cycloalkanes, alkanes, toluene derivatives or ethers.

Pseudo-tetrahedral coordination geometries were observed around the zinc(II) centers in both complexes, constructed by one oxygen atom from a formate anion and three nitrogen atoms from one pzH and two pyrazolato in 1 or one dmpzH and two 3,5-dimethylpyrazolato in 2. The bulk of these materials are consolidated by weak and strong N-H center dot center dot center dot O, C-H center dot center dot center dot O, C-N center dot center dot center dot O and C-H center dot center dot center dot pi, N-H center dot center dot center dot pi and C-O center dot center dot center dot O intra/intermolecular interactions resulting to zigzag networks containing empty voids.

A sequential and general strategy has been successfully developed for the synthesis of spiropyrazolone scaffolds. This intriguing transformation of the asymmetric multicomponent catalysis process was realized with the combination of Michael addition/chlorination/nucleophilic substitution in a one-pot sequence, giving rise to a series of spiropyrazolones with fully substituted cyclopropanes and spiro-dihydrobenzofurans containing continuous stereogenic centers in good yields with excellent stereoselectivities.

An article Correlation between Equilibrium Constant and Stabilization Energy: A Combined Approach Based on Chemical Thermodynamics, Statistical Thermodynamics, and Density Functional Reactivity Theory WOS:000515216300008 published article about DFRT BASED APPROACH; BASIS-SET; NUCLEOBASES; UNDERSTAND; CLUSTERS; HARDNESS; BINDING; ADDUCT in [Hamid, Aabid; Roy, Ram Kinkar] Birla Inst Technol & Sci, Dept Chem, Pilani 333031, Rajasthan, India in 2020.0, Cited 28.0.

In the present work, an attempt is made to establish the correlation between equilibrium constant and stabilization energy [Delta E-SE(AB)] generated from density functional reactivity theory (DFRT). The reactions chosen here are of type A + B (sic) AB (i.e., adduct formation type) between an electron acceptor, A, and an electron donor, B. The representative acceptors are methyltrioxorhenium (MTO) and substituted benzaldehydes whereas donors are 26 mono- and bidentate ligands (having N-donors) and semicarbazide. The trends of experimentally generated equilibrium constant (K) values match with those of Delta E-SE(AB) in most of the cases, both in gas phase as well as in solvent. Justification of this reliable correlation is provided analytically using the expressions of standard Gibbs free energy of reaction (i.e., Delta(r)G(theta)) and the stabilization energy expression generated by DFRT. A further analytical explanation (albeit not very rigorous) is provided through statistical thermodynamics showing how equilibrium constant (K) is related to Delta E-SE(AB) for reactions of the type A + B (sic) AB, where either A or B is a common species.

We report the first asymmetric total synthesis and structural determination of calixanthomycin A. Taking advantage of a modular strategy, a concise approach was developed to assemble the hexacyclic skeleton with both enantiomers of the lactone A ring. Stereoselective glycosylation coupled the angular hexacyclic framework with a monosaccharide fragment to produce calixanthomycin A and its stereoisomers. This enable us to determine and assign the absolute configuration of C-25 (25S) and monosaccharide (derivative of L-glucose).

We have reported the synthesis, characterization, and catalytic applications of amorphous iron nanoparticles (FeNPs) using aqueous leaves extract of renewable natural resourceBoswellia serrataplant. Synthesized FeNPs were stabilized in situ by the addition of aqueous pod extracts ofAcacia concinnaas a biosurfactant (pH 3.11). The structural investigation of biosynthesized nanoparticles was performed using UV-visible spectroscopy, X-ray diffraction analysis, selected area electron diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and BET analysis. The FeNPs were amorphous in nature with average particle size similar to 19 nm and successfully employed as heterogeneous catalyst for the synthesis of quinoxaline, benzimidazole, and pyrazole derivatives in aqueous medium at ambient conditions. The FeNPs could be recycled up to five times with modest change in the catalytic activity. [GRAPHICS] .
