Aerobic organisms must rely on abundant intracellular thiols to reductively protect various vital functional units, especially ubiquitous zinc(II) thiolate sites of proteins, from deleterious oxidations resulting from oxidizing environments. Disclosed here is the first well-defined model study for reactions between zinc(II) thiolate complexes and copper(II) complexes. Among all the studied ligands of copper(II), diethyldithiocarbamate (DTC) displays a unique redox-tuning ability that enables copper(II) to resist the reduction by thiols while retaining its ability to oxidize zinc(II) thiolates to form disulfides. This work proves for the first time that it is possible to develop oxidants to discriminate between thiols and zinc(II) thiolates, alluding to a new chemical principle for how oxidants, especially universal anticancer Cu(DTC)(2), might circumvent the intracellular reductive defense around certain zinc(II) thiolate sites of proteins to kill malignant cells.

The one pot reaction between 1,3-diaminopropane, 3,5-dimethylpyrazole and paraformaldehyde afforded 1,3-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)hexahydropyrimidine 1 in an excellent yield. The reaction of 1 with one equivalent of N-bromosuccinimide in DME gave the oxidized product 2 ; the same reaction in the presence of 4 equivalents of NBS yielded the pyrazole ring brominated product. Treatment of 2 with NH4PF6 gave its PF6- salt 3 . Conversely, its BF4- salt was obtained directly from the reaction of AgBF4 with 1. Treatment of 3 with palladium(II) precursors gave two monomeric trans chelated complexes containing acetate and chloride ions as their PF6- salts. Conversely, 1 reacts with palladium(II) source to give the dimeric 20-membered palladacycle. The monomeric complexes are rigid molecules, whereas the dimer complex is fluxional as shown by their H-1 NMR spectra. From the low temperature NMR study of the dimer complex the broad signals in the room temperature NMR spectrum are attributed to the fast interconversion between its conformers. All compounds were characterized by both spectroscopic and X-ray methods, and in some cases by CHN analysis. DFT calculations were performed to understand the formation of the chelate complex against its anticipated NHC complex containing the 6-membered ring and the binuclear complex against a monomeric complex in terms of 5- and 6-membered ring strain energies.

The synthesis and photophysical properties of the heteropolynuclear Pt-Ag complex having cyclometalated rollover bipyridine ligands (bpy*) and bridging pyrazolato ligands are reported. The Pt2Ag2 complex was synthesized by two step reactions from a Pt(II) complex precursor having the rollover bpy* ligand, [Pt(bpy*)(dmso)Cl], with 3,5-dimethylpyrazole (Me(2)pzH) and a subsequent replacement of NH protons in the Me(2)pzH moieties with the Ag(I) ion. The Pt2Ag2 complex exists as a mixture of U- and Z-shaped isomers in solution, whose structures were clearly determined by single-crystal X-ray structural analyses. NMR studies using the single crystals revealed rapid isomerization of the Pt2Ag2 complexes in solution, although the Pt2Ag2 structures were supported effectively by the multiple metal-metal interactions. Furthermore, the Pt2Ag2 framework can capture a Ag(I) ion during the U-Z isomerization to afford a Pt2Ag3 core with the formation of Pt. Ag dative bonds. The Pt2Ag3 complex showed further aggregation to form a dimer structure in the presence of coordinating solvent via the crystallization process. The formation of Pt. Ag dative bonds significantly changes the emission energy from the Pt2Ag2 complex, while the emission spectra of U- and Z-isomers of Pt2Ag2 complex almost coincide with each other and their emissive properties are very similar. The density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations revealed the effects of additional Ag(I) ion on the photophysical properties of the heteropolynuclear Pt-Ag complexes bearing the rollover bpy* ligands.

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.

The standard molar enthalpies of vaporization of alkyl-pyrazoles were derived from their vapor pressure-temperature dependence measured by the transpiration method as well as indirectly using solution calorimetry. Thermodynamic data on vaporization processes available in the literature were collected, evaluated, and combined with our own experimental results. Additional combustion experiments on the highly pure 1-methyl-pyrazoles helped to resolve ambiguity in the enthalpy of formation for this compound. We have evaluated and recommended a set of vaporization and formation enthalpies for the alkyl-pyrazoles at 298.15 K as the reliable benchmark properties for further thermochemical calculations. Gas phase molar enthalpies of formation of alkyl-pyrazoles calculated by the high-level quantum-chemical G4 and G3MP2 methods were in an excellent agreement with the recommended experimental data. The hydrogenation/dehydrogenation reaction enthalpies of alkyl-pyrazoles were calculated and compared with the data for other potential liquid organic hydrogen carriers. (C) 2018 Elsevier Ltd.

The synthesis of new cationic macrocyclic host molecules is described. These macrocycles are comprised of glycoluril oligomers linked to two pyrazolium groups, which form part of a cationic wall facing into their cavities. A number of derivatives have been prepared with an objective to increasing the cavity size, and each new product has been fully characterized. Preliminary investigations of pK(a)s of Me(10)Tu-[3](2+) and an interaction of L-glutamine indicate a potential for binding anionic molecules that also carry H-bond donor groups.

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.
