The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

Herein a series of novel bis(pyrazol-1-ylmethyl)pyridine-ligated Cu(i) complexes, C1-C4, bearing different donating groups [[H(C1), Me(C2), t-Bu(C3), Ph(C4)])] on the pyrazole rings, were synthesized and investigated as pre-catalysts in chemical and electrocatalytic water oxidation reactions. Ligands, 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L1), 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L2), 2,6-bis((3,5-di-tert-butyl-1H-pyrazol-1-yl)methyl)pyridine (L3), and 2,6-bis((3,5-diphenyl-1H-pyrazol-1-yl)methyl)pyridine (L4) were reacted with Cu(MeCN)(4)PF6 to form complexes C1-C4 respectively. Cerium ammonium nitrate (CAN), sodium m-periodate, and sodium persulfate were investigated as chemical oxidants in chemical water oxidation. Complexes C1-C4 showed catalytic activity towards chemical water oxidation in the presence of CAN as the primary oxidant at 25 degrees C. Complex C2 was the most active with a turnover number (TON) of 4.6 and a turnover frequency (TOF) of 0.31 s(-1). The least active catalyst was complex C4, with a TON of 2.3 and a TOF of 0.0086 s(-1). This observed difference in catalytic activity between the complexes illustrated the key role that electronic effects play during catalysis. Other oxidants evaluated with C2 were sodium m-periodate (TON, 3.77; TOF 0.14 s(-1)) and sodium persulfate (TON, 4.02; TOF 0.044 s(-1)) however, CAN exhibited the greatest activity. Complexes C1-C4 were investigated in electrocatalytic water oxidation at a neutral pH of 6.5. Complex C2 was the most active in electrocatalytic water oxidation as well, exhibiting an overpotential of 674 mV and TOF of 9.77 s(-1) (at 1.7 V vs. NHE), which is better than most reported copper(ii) complexes. These Cu(i) complexes C1-C4 show potential as efficient chemical and electrocatalytic water oxidation catalysts, which can be achieved by fine-tuning the steric and electronic properties of the catalysts.

Unsymmetrical pincers have been shown to be better than the corresponding symmetrical pincers in several catalysis reactions. A new unsymmetrical PNN propincer, 2-(3,5-dimethylpyrazolylmethyl)-5-(diphenylphosphinomethyl)-pyrrole (1), was synthesized from pyrrole through Mannich bases in a good yield. In addition, the new byproduct 2-(3,5-dimethylpyrazolylmethyl)-5-(dimethylaminomethyl)-N-(hydroxymethyl)pyrrole was also isolated. The reaction of 1 with [PdCl2(PhCN)(2)] and Et3N in toluene yielded [PdCl-{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (2). The analogous reaction between 1 and [NiCl2(DME)] or NiX2 (X = Br, I) in the presence of NEt3 in acetonitrile afforded [NiX{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (3; X = Cl, Br, I). All complexes were structurally characterized. The norbornene polymerization behaviors of the unsymmetrical pincer complexes 2 and 3 in the presence of MMAO or EtAlCl2 were compared with those of the symmetrical pincer complexes chloro[2,5-bis(3,5-dimethylpyrazolylmethyl)pyrrolido]-palladium(II) (NNN), chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]palladium(II), and chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]nickel(II) (PNP) at different temperatures. The PNN and NNN complexes exhibited far greater activity on the order of 10(7) g of PNB/mol/h, with quantitative yields in some cases, in comparison to the PNP pincer palladium and nickel complexes. This trend was also supported by the Pr-i group substituted PNP nickel and palladium pincer complexes. These polymerization behaviors are explained using steric crowding around the metal atom with the support of NMR studies and suggested that the activity increases as the N-pyrazole donor increases. Polymers were characterized by H-1 NMR, IR, TGA, and powder XRD methods.

The industrial process of hydroformylation or the oxo process has been used for many years in the production of aldehydes from alkenes. Different metals have been used as efficient catalysts for hydroformylation, in which linear and branched aldehydes are the products obtained; therefore, the development of new catalysts for hydroformylation with high selectivity to aldehydes is important. Rhodium complexes 6-9 were synthesized using [RhCl(CO)(2)](2), or [RhCl(COD)](2), with either pyrazolylpyridyl N ‘ N ‘ N pincer ligands or a pyrazolylpyridyl N ‘ N ligand. These complexes were then evaluated as catalyst precursors in the hydroformylation reaction using a variety of alkenes. The catalysts all showed activity in hydroformylation but the most active catalyst was methyl-substituted pyrazolyl-rhodium complex 7 following optimization of temperature, syngas pressure and amount of catalyst. Other olefinic substrates were used for hydroformylation in the presence of 7 under the optimum hydroformylation conditions. Undecene and dodecene as substrates only showed minimal formation of aldehydes with predominantly isomerization of the alkene being observed.

The cerium(IV) pyrazolate complexes [Ce(Me(2)pz)(4)](2)and [Ce(Me(2)pz)(4)(thf)] initiate beta-hydride abstraction of the bis(dimethylsilyl)amido moiety, to afford a heteroleptic cerium(IV) species containing a dimethylpyrazolyl-substituted silylamido ligand, namely [Ce(Me(2)pz)(3)(bpsa)] (bpsa=bis((3,5-dimethylpyrazol-1-yl)dimethylsilyl)amido; Me(2)pz =3,5-dimethylpyrazolato), along with some cerium(III) species. Remarkably, the nucleophilic attack of the pyrazolyl at the silicon atom and concomitant Si-H-bond cleavage is restricted to the tetravalent cerium oxidation state and appears to proceed via the formation of a transient cerium(IV) hydride, which engages in immediate redox chemistry. When [Ce(Me(2)pz)(4)](2)is treated with [Li{N(SiMe3)(2)}], that is, in the absence of the SiH functionality, any redox chemistry did not occur. Instead, the ceric ate complex [LiCe2(Me(2)pz)(9)] and the stable mixed-ligand ceric species [Ce(Me(2)pz)(2){N(SiMe3)(2)}(2)] were obtained.

Synthesis of the multidentate coordinated chelate N3C-H-2, composed of a linked functional pyridyl pyrazole fragment plus a peripheral phenyl and pyridyl unit, was obtained using a multistep protocol. Preparation of Ir(III) metal complexes bearing a N3C chelate in the tridentate (kappa(3)), tetradentate (kappa(4)), and pentadentate (kappa(5)) modes was executed en route from two nonemissive dimer intermediates [Ir(kappa(3)-N3CH)Cl-2](2) (1) and [Ir(kappa(4)-N3C)Cl](2) (2). Next, a series of mononuclear Ir(III) complexes with the formulas [Ir(kappa(4)-N3C)Cl(py)] (3), [Ir(kappa(4)-N3C)Cl(dmap)] (4), [Ir(kappa(4)-N3C)-Cl(mpzH)] (5), and [Ir(kappa(4)-N3C)Cl(dmpzH)] (6), as well as diiridium complexes [Ir-2(kappa(5)-N3C)-(mpz)(2)(CO)(H)(2)] (7) and [Ir-2(kappa(5)-N3C)-(dmpz)(2)(CO)(H)(2)] (8), were obtained upon treatment of dimer 2 with pyridine (py), 4-dimethylaminopyridine (dmap), 4-methylpyrazole (mpzH), and 3,5-dimethylpyrazole (dmpzH), respectively. These Ir(III) metal complexes were identified using spectroscopic methods and by X-ray crystallographic analysis of representative derivatives 3, 5, and 7. Their photophysical and electrochemical properties were investigated and confirmed by the theoretical simulations. Notably, green-emitting organic light-emitting diode (OLED) on the basis of Ir(III) complex 7 gives a maximum external quantum efficiency up to 25.1%. This result sheds light on the enormous potential of this tetradentate coordinated chelate in the development of highly efficient iridium complexes for OLED applications.

Lots of ionic liquids have been utilized as catalyst for the coupling reaction of carbon dioxide with epoxides, however, catalyzed conditions could not be regarded as benign, especially when no co-catalyst and/or organic solvent is involved. A series of hydroxyl-functionalized pyrazolium ionic liquids are firstly synthesized. They would efficiently catalyze the cycloaddition of carbon dioxide and propylene oxide under 110 degrees C and 1.0 MPa carbon dioxide initial pressure with 1 mol% catalyst during 4 h resulting in the product yield of 91.2%. The catalytic condition is greatly refined as compared with other single-component ionic liquids with simple anion. Simultaneously, the effect of reaction temperature, amount of catalyst, carbon dioxide initial pressure, and reaction time is explored along with the reusability of catalyst For most of epoxides with terminal substituted group, HEEPzBr presents acceptable catalytic activity. The difference of HEMPzBr, HEEPzBr, and HPEPzBr is also explored by the density functional theory calculations. (C) 2019 Elsevier B.V. All rights reserved.

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.
