New cis-(1,2-azole)-aquo bis(2,2′-bipyridyl)-ruthenium(II) (1,2-azole (az*H) = pzH (pyrazole), dmpzH (3,5-dimethylpyrazole), and indzH (indazole)) complexes are synthesized via chlorido abstraction from cis-[Ru(bipy)(2)Cl(az*H)]OTf. The latter are obtained from cis-[Ru(bipy)(2)Cl-2] after the subsequent coordination of the 1,2-azole. All the compounds are characterized by H-1, C-13, N-15 NMR spectroscopy as well as IR spectroscopy. Two chlorido complexes (pzH and indzH) and two aquo complexes (indzH and dmpzH) are also characterized by X-ray diffraction. Photophysical and electrochemical studies were carried out on all the complexes. The photophysical data support the phosphorescence of the complexes. The electrochemical behavior of all the complexes in an Ar atmosphere indicate that the oxidation processes assigned to Ru(II) -> Ru(III) occurs at higher potentials in the aquo complexes. The reduction processes under Ar lead to several waves, indicating that the complexes undergo successive electron-transfer reductions that are centered in the bipy ligands. The first electron reduction is reversible. The electrochemical behavior in CO2 media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(p)(Ar)] ranged from 2.9 to 10.8. Controlled potential electrolysis of the chlorido and aquo complexes affords CO and formic acid, with the latter as the major product after 2 h. Photocatalytic experiments in MeCN with [Ru(bipy)(3)]Cl-2 as the photosensitizer and TEOA as the electron donor, which were irradiated with >300 nm light for 24 h, led to CO and HCOOH as the main reduction products, achieving a combined turnover number (TONCO+HCOO-) as high as 107 for 2c after 24 h of irradiation.

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.

The controlled generation of hydrogen sulfide (H2S) under biologically relevant conditions is of paramount importance due to therapeutic interests. Via exploring the reactivity of a structurally characterized phenolate-bridged dinuclear zinc(II)-aqua complex {LZnII(OH2)}(2)(ClO4)(2) (1a) as a hydrolase model, we illustrate in this report that complex 1a readily hydrolyses CS2 in the presence of Et3N to afford H2S. In contrast, penta-coordinated [Zn-II] sites in dinuclear {(LZnII)(2)(mu-X)}(ClO4) complexes (7, X = OAc; 8, X = dimethylpyrazolyl) do not mediate CS2 hydrolysis in the presence of externally added water and Et3N presumably due to the unavailability of a coordination site for water at the [Zn-II] centers. Moreover, [Zn-II]-OH sites present in the isolated tetranuclear zinc(II) complex {(LZnII)(2)(mu-OH)}(2)(ClO4)(2) (4) react with CS2, thereby suggesting that the [Zn-II]-OH site serves as the active nucleophile. Furthermore, mass spectrometric analyses on the reaction mixture consisting of 1a/Et3N and CS2 suggest the involvement of zinc(II)-thiocarbonate (3a) and COS species, thereby providing mechanistic insights into CS2 hydrolysis mediated by the dinuclear [Zn-II] hydrolase model complex 1a.

The reaction of pyrazole derivatives ( pyrazole (Pz), 3-methylpyrazole (MPz) and 3,5-dimethylpyrazole (DMPz)) with terephthaloyl dichloride (TD) in the presence of Et3N afforded the desired products, 1,4-bis(pyrazolylcarbonyl)benzene (1), 1,4-bis(3-methylpyrazolylcarbonyl)benzene (2) and 1,4-bis(3,5-dimethylpyrazolylcarbonyl)benzene (3). Good quality crystals were isolated and diffraction data for single crystal were collected which revealed that compounds 1-3 are monoclinic with space group P21/n, C2/c and P21/c, respectively. These compounds were obtained as a result of C-N coupling reaction between the acid chloride and pyrazol derivatives with the intent to explore their structure in solution as well as solid state. Density function theory (DFT) calculations using B3LYP and CAM-B3LYP functionals with 6-311G(d,p) basis set were performed to explore geometric and electronic properties of compounds. The Root Mean Square Error (RMSE) has also been calculated for the values of geometric parameters, indicating a good agreement with experimental findings. Moreover, frontier molecular orbitals (FMOs) and natural bond orbitals (NBOs) analyses were carried out through B3LYP/6-311G(d,p) level of theory. The linear polarizability (alpha) values of nonlinear optical (NLO) analysis were calculated with the same level of theory and basis set as FMO but under different solvent conditions. Time Dependent Density Functional Theory (TD-DFT) study of these pyrazole substituted derivatives was performed aiming to investigate UV-Visible behavior. The stability of molecule has been additionally analyzed by Hirshfeld surface analysis in addition to NBO analysis. The calculated HOMO and LUMO energies from FMO assisted in calculating global reactivity parameters (Chemical hardness, chemical softness, electronegativity, EA, IP and electrophilicity). Natural population analysis (NPA) and Molecular electrostatic potential (MEP) were also performed to obtain insights about the reactivity of compounds 1-3. Theoretical calculations indicate that these compounds have considerable low reactivity and can be used for development of coordination chemistry under optimum conditions. (c) 2019 Elsevier B.V.

The present study pertains to the synthesis and characterizations of nine novel mixed-ligand complexes of [Zn(Hdmpz)(2)(L1)(2)] (1) (dmpz = 3,5-dimethylpyrazolate, Ll = 2-bromobenzoate), [Zn(Hdmpz)(2)(L2)(2)] (2) (L2 = 4-tert-butylbenzoate), Zn(Hdmpz)(2)(L3)(2) (3) (L3 = 2-thiophenoate), [Zn(Hdmpz)(2)(L4)(2)] (4) (L4 = 4-methylsalicylate), [Cd(Hdmpz)(2)(L5)(2)](2) (5) (L5 = 2,6-dihydroxy benzoate), [Cd (Hdmpz)(2)(L6)(2)](2).2H(2)O (6) (L6 = 3-(4-methoxy-phenylcarbamoyI)-acrylate), [Zn(Hdmpz)(2)(L7)](2) (7) (L7 = acetylenedicarboxylate), [Zn(Hdmpz)(2)(L8)] (8) (L8 = 1,2-phenylenediacetate), and [Cd(Hdmpz)(L9) (H2O)(2)].H2O (9) (L9 = 3-nitrophthalate). The resulting complexes were formulated via EA, IR, and SCXRD, and the TGA of all the complexes was also evaluated. The X-ray studies reveal that these complexes present mononuclear to dinuclear structures with tetrahedral geometry around each Zn2+, and octahedral/pentagonal bipyramidal geometry for Cd2+ The Hdmpzs in all compounds are coordinated only in monodentate fashion with its neutral N. The carboxylates at 1-4 and 3-9 function only as unidentate coordination units, the CO2- in 5 has the chelating bidentate coordination mode. Compound 6 contains both unidentate bridging and bidentate chelating COO-. The free carboxylate 0 at 2-4 and 7-8 accept the intramolecular N-H…O H-bonds, at 1 and 7 the uncoordinated O participate in the intermolecular N-H…O H-bonds. For 6 there is intermolecular N H-0 H-bond from the NHCO and H2O, and intramolecular N-H…O H-bonds from the NH at Hdmpz, the NHCO (acceptor), and one 0 at the bismonodentate coordinated COO-. One anion at 6 also gives the intramolecular N H-H-bonds from the NHCO(donor) and one O at the bismonodentate coordinated COO-. The intermolecular N-H…O H-bonds are from the phenol at both 4 and 5, and from the H2O at 9. The CH3 at Hdmpz in all compounds are participated in the noncovalent bonds except 3. The intricate intra-and intermolecular N-H…O and O-H…O H-bonds as well as C-H…N, C-H, O..O, Br…O, CH3…CH, CH2…C, CH3…C, C-H..O, CH2…O, CH3…O, C-H…S, C-H…CH3- rt, and pi…phi associations are elucidated by the X-ray crystallographic studies, which unite the discrete units into high-dimensional ordered supramolecular structures.

A practical means to quantify the response of the rates of net N mineralization and denitrification over a wide range of soil water contents is generally lacking. This study examined the potential to use a nitrification inhibitor (NI) assay system to simultaneously estimate the rates of net N mineralization and denitrification, and applied the NI assay to assess the effect of water content on net N mineralization and denitrification rates in two soils with contrasting soil texture. The compound 3,5-dimethylpyrazole (DMP) applied at a rate of 200 mg kg(-1) was found to provide essentially complete inhibition of nitrification over the duration of the soil incubation for two soils with contrasting soil texture (clay loam vs. sandy loam) and over a range of soil water contents (35%, 55%, and 85% water-filled pore space). This allowed net N mineralization to be estimated as the accumulation of soil ammonium (NHthorn 4) and of denitrification as the disappearance of added nitrate (NO3-). Addition of DMP resulted in a small increase in soil respiration rate but did not appear to influence the rate of net soil N mineralization. The NI assay provides a practical means to quantify the rates of net N mineralization and denitrification simultaneously over a wide range of soil water contents. The assay can be readily scaled up to routinely test multiple soils in an efficient manner, has limited material costs, and is also relatively simple to perform.

A number of novel 6-R-isoxazolo[4,3-b]pyridines were synthesized and their reactions with neutral C-nucleophiles (1,3-dicarbonyl compounds, pi-excessive (het)arenes, dienes) were studied. The reaction rate was found to be dependent on the nature of the substituent 6-R. The most reactive 6-nitroisoxazolo[4,3-b]pyridines are able to add C-nucleophiles in the absence of a base under mild conditions. In addition, these compounds readily undergo [4+2]-cycloaddition reactions on aromatic bonds C=C(NO2) of the pyridine ring, thus indicating the superelectrophilic nature of 6-NO2-isoxazolo[4,3-b]pyridines.
