A reaction of [Cu(MeCN)(4)]BF4 with PzH (3,5-dimethyl-pyrazole) and BINAP [2,20-bis(diphenylphosphino)-1,10-bi-naphthyl] leads to the formation of mononuclear Cu-I complex [Cu(PzH)(BINAP)]BF4 containing the molecule of non-deprotonated pyrazole and one BINAP ligand with two phosphorus atoms chelating the metal. This complex exhibits a bright phosphorescence originating from the (3)(M+L)LCT state at room temperature. At 77 K, the emission is splitted into two components: (3)(M+L)LCT and (LC)-L-3 transitions.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid methyl esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was experimentally detected that catalysts containing OH-groups (alcohols, glycols, glycerol and aminoalcohols) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations. Catalysts concentration effects on the reaction rate were also investigated.

Eight Pyrazole ligands which are prepared by condensation of different amines with Pyrazole and 3,5-dimethylpyrazole, then characterized using FTIR. This analysis was recorded using KBr pellets on FTIR-8400S spectrometer, and then the spectra are compared with the ones calculated by the Density Functional Theory (DFT) calculations with GAUSSIAN 09W suite. Experimental and calculated vibrational spectra demonstrate a good correlation with some difference in % T and frequency (cm(-1)) shown in the theoretical spectra due to the presence of all predicted vibrational modes. The optimized structure, HOMO, LUMO orbitals and some other quantum descriptors were also determined to reveal their chemical reactivity properties. The similarities and the differences between the theoretical and the experimental vibrational analysis of all the prepared ligands have been highlighted. The calculated FTIR spectra by DFT shows perfect agreement with the experimental ones and generated positive value of vibrations indicate calculations are at the global minima. (c) 2019 Elsevier Ltd.

In this study, a novel pyrazole-carbodithioate-based chain transfer agent (CTA) featuring an aldehyde group (CTA-CHO) was designed and synthesized for RAFT polymerization. The obtained CTA-CHO was employed for the RAFT polymerization of styrene to afford well-defined polystyrenes bearing an aldehyde at their chain ends with low D values (similar to 1.1). In addition, the reactivity of the aldehyde moiety at the end of the chain was precisely evaluated, while the Passerini three-component reaction was successfully performed on the aldehyde group.

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.

An efficient Zn(OTf)(2)-catalyzed regioselective C-N bond making reaction between a bunch of aryl/heteroaryl-substituted para-quinone methides as ideal 1,6-acceptors and various aromatic/non-aromatic aza-heterocycles bearing N-H moiety namely carbazoles, pyrazoles, indazole, benzotriazole and saccharin is reported. This 1,6-aza-Michael technique delivers predominantly NI-diarylmethyl-substituted heterocyclic scaffolds bearing a valuable phenolic moiety in good to high yields with an excellent regioselectivity. Furthermore, this LUMO lowering catalytic system allows different kinds of useful functionalities and excels with broad substrates under mild conditions. Importantly, our control experiments suggested that N2-adducts of indazole, benzotriazole and 3-methyl pyrazole as minor isomers were progressively converted into N1-adducts during the reaction via a retro-aza-Michael reaction triggered by Zn(OTf)(2), offering excellent regioselectivities of the products.

Azoles are emerging contaminants that are resistant to biodegradation during wastewater treatment. Their presence has been widely reported in wastewater effluents and receiving waters. In this work, the potential inhibition of nitrification process by six different azole compounds in wastewater treatment plants was investigated in batch bioassays. The azoles studied included three diazoles: pyrazole (Pz); 1-methylpyrazole (MePz); 3,5-dimethylpyrazole (DMePz); and three triazoles: 1,2,4-triazole (Tz); benzotriazole (BTz); and 5-methyl benzotriazole (MeBTz). The concentration of azoles causing 50% inhibition (IC50) increased (azoles became less inhibitory) in the following order (mg L-1): BTz (1.99) < MeBTz (218) < Pz (2.69) < Tz (3.53) < DMePz (17.3) < MePz (49.6). No clear structure-inhibitory relationships were found using Log P and pKa as structural properties. The toxicity of any given azole may be related to the role of substituent groups on disabling/enabling binding to the active sites of metallo-enzymes in nitrifying microorganisms. This is exemplified by the low toxicity of MePz, which has a cyclic N blocked by a methyl group. The observed inhibition caused to nitrifying bacteria is more severe than their cytotoxicity to other target organisms (e.g., methanogens and heterotrophic bacteria), suggesting a specific inhibition to the copper-containing enzyme, ammonium monooxygenase, in ammonia oxidizing nitrifying microorganisms.

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.

Recommanded Product: 67-51-6. I found the field of Chemistry very interesting. Saw the article Effect of benzoic acid substituents and additional functional groups of ancillary ligands in modulating the nuclearity and aggregation behavior of transition metal carboxylates published in 2019.0, Reprint Addresses Murugavel, R (corresponding author), Indian Inst Technol, Dept Chem, Bombay 400017, Maharashtra, India..

Structural modulation of transition metal carboxylates has been studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids. A series of neutral transition metal benzoates [Cu(tbba)(2)(imH)(2)] (1), [Cu(tipba)(2)(2,4,6-collidine)(2)] (2), [Co(tbba)(2) (dmpH)(2)] (3), [Co(tipba)(2)(imH)(2)] (4), [M (tmba)(2)(pymeH)(2)] (M = Cu (5), Co (6) and Zn (7)), [Zn(tmba)(2)(pydmeH(2))] (8), [Cu-2(tmba)(2)(pydmeH(2))(2)] [(tmba)(2)(tmbaH)(2)] (9) and [Zn-2(dmp)(2) (tbba)(2)(dmpH)(2)] (10) have been isolated as products from the reaction between the respective metal acetates and substituted benzoic acids (acids used: 4-tert-butylbenzoic acid (tbbaH), 2,4,6-triisopropylbenzoic acid (tipbaH), 2,4,6-trimethylbenzoic acid (tmbaH)) and N-donor auxiliary ligands (imidazole (imH), 3,5-dimethylpyrazole (dmpH), 2,4,6-collidine, 2-pyridinemethanol (pymeH), and pyridine-2,6-dimethanol (pydmeH(2))). The new complexes have been characterized by both analytical and spectroscopic methods. The molecular structures of 1-10 have further been established by single crystal X-ray diffraction studies. The complexes 1-8 are mononuclear, while compounds 9 and 10 have been found to be dinuclear due to the role of benzoic acid in 9 and pyrazolate anion as bridging ligand in 10. The geometry around the metal ion is square-planar in 1 and 2, tetrahedral in 3, 4 and 10, octahedral in 5-7 and 9 and trigonal-bipyramidal in 8. Complexes with ligands that contain additional functional groups such as > NH and -OH are involved in hydrogen bonding interactions. These weak interactions lead to the formation of 1-D linear polymers or 2-D sheets.
