An efficient and straightforward method for the synthesis of new and versatile sulfonyl-functionalized allylic amines through the selective copper-catalyzed aza-1,6-conjugate addition of heterocycles or arylamines to 1,4-disubstituted-1,3-dienyl sulfones has been developed. This catalytic process is promoted by a combination of an easily prepared and sterically demanding N-heterocyclic carbene-based copper complex and KOt-Bu under mild reaction conditions to provide a broad range of (E)-allylic amines with excellent regio- and stereoselectivities.

Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with a new sulfonated derivate from bis(3,5-dimethylpyrazol-1-yl)methane (LSA) was electrochemically synthesized and characterized by cyclic voltammetry, chronoamperometry, scanning electron microscopy, Raman spectroscopy and ultraviolet/visible spectroscopy. In addition, LSA was also fully characterized. A PEDOT:LSA modified electrode was used to study the electrochemical detection of dopamine in the presence of ascorbic and uric acid. The use of this new dopant increased the sensitivity and reduced the detection limit compared with the values observed for PEDOT doped with perchlorate.

In this work, three novel nonmetallic pentazole salts (6-8) based on furazan or 4-nitropyrazole were synthesized. Some coplanar groups were introduced into the compounds to improve the planarity of the crystal packing. 4-Amino-1,2,5-oxadiazole-3-carbohydrazonamide pentazolate (6), 5-(4-amino-1,2,5-oxadiazol-3-yl)-4H-1,2,4-triazole-3,4-diamine pentazolate (7), and 5,5′-(4-nitro-1H-pyrazole-3,5- diyl)-bis(4H-1,2,4-triazole-3,4-diamine) pentazolate (8) all show more stable pi-pi stacking and exhibit superior thermal stability (110.5-116.4 degrees C) than most other reported nonmetallic pentazole salts (T-onset: 80-110 degrees C), and compound 8 has the highest crystal density (1.722 g.cm(-3)/173 K) of nonmetallic pentazole salts to date. All salts have been thoroughly characterized by NMR (H-1 and C-13) spectroscopy, infrared (IR), Roman (RA), and elemental analysis. The decomposition temperature of all salts displays more than 110 degrees C, which is measured by differential scanning calorimetry (DSC). These compounds all shows low sensitivity (IS > 35 J, FS > 360 N) measured by standard BAM methods. Glycidyl azide polymer (GAP) based propellant formula with the addition of salt 6 or 7 shows a higher specific impulse (6, I-sp = 262.1 s; 7, I-sp = 263.9 s) than that of RDX (I-sp = 259.0 s). This study can provide a new crystal engineering way for the synthesis of pentazole salt to solve the problem of low density and poor stability.

Chiral phosphoric acid based organocatalysis and visible-light photocatalysis have both emerged as promising technologies for the sustainable production of fine chemicals. In this context, we have envisioned the design and the synthesis of a new class of chimeric catalytic entities that would feature both catalytic capabilities. Given their multitask nature, such catalysts would be particularly attractive for the development of new catalytic transformations, tandem processes in particular. Toward this goal, several BINOL-based chiral phosphoric acid backbones presenting one or two visible-light-sensitive thioxanthone moieties have been prepared and studied. The utility of these new photoactive chiral organocatalysts is then demonstrated in the enantioselective tandem three-component electrophilic amination of enecarbamates. Of note, the C-1-symmetric organo/photocatalyst has shown a better catalytic activity than those presenting a C-2 symmetry.

Two new coordination compounds viz. [Ni(2,6-PDC)(Hdmpz)(H2O)(2)]center dot H2O (1) and [Zn(3-CNpy)(2)Cl-2] (2) (2,6-PDC = 2,6-pyridinedicarboxylate, Hdmpz = 3,5-dimethylpyrazole, 3-CNpy = 3-cyanopyridine) have been synthesized and characterized using elemental analysis, thermogravimetric analysis, electronic, infrared spectroscopy and single crystal X-ray diffraction techniques. Crystal structure analyses reveal the presence of supramolecular assemblies involving interesting dimers with unconventional contacts in the compounds. DFT (Density Functional Theory) calculations on the supramolecular dimers in the crystal structure of 1 reveal that the sum of contributions of anion-pi, pi-pi and other long range interactions due to the approximation of the bulk monomers is energetically significant. Molecular Electrostatic Potential (MEP) surface and Quantum Theory of Atoms in Molecules (QTAIM) analyses on the interesting supramolecular dimers of the crystal structures of 2 reveal the presence of unconventional anion center dot center dot center dot pi contacts involving coordinated chlorido ligands and C-H center dot center dot center dot pi(nitrile) interactions involving the pi-system of the nitrile moiety of 3-cyanopyridine. Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%). It is interesting that compound 1has excellent cytotoxic potency with IC50 closer to cisplatin and can bind different biological targets with similar signalling pathways. Structure activity relationship (SAR) analyses of 1 and 2 based on pharmacophore modelling reveal that the molecular features associated with the structures of the compounds play important role in the biological activities.

Self-healing materials can partially or completely heal the damage done to them, and it is expected that their original function will be thereby restored. Herein, we report a novel self-healing polyvinyl (Sh-PV) containing functional polymer that reacts to thermal and ultraviolet (UV) energy. The structure of Sh-PV was characterized by fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (H-1 NMR). In addition, aluminum oxide (Al2O3) inorganic nanoparticles (NPs) were added and hybridized to improve their poor self-healing efficiency and surface hardness of the coated thin film. Mechanical nanoscratch testing and scanning probe microscopy (SPM) imaging of surface using a nanoindenter were performed to investigate the healing ability of self-healing thin films. The organic-inorganic hybrid self-healing polymer thin film exhibited a 10 % improvement in surface hardness as well as 100 % healing against nanoscale damage compared to virgin self-healing polymers. Here, we discuss and evaluate the optimized method and mechanism of the self-healing system based on the results of self-healing materials and physical recovery methods for healing surface damage.

Equimolar reactions of Et2Zn with 3,5-dimethylpyrazole (H-pz(Me2)), 3,5-di-iso-propylpyrazole (H-pz(iPr2)), 3,5-di-tert-butylpyrazole (H-pz(tBu2)) and indazole (H-ind) were investigated in toluene or tetrahydrofuran (as a coordinating solvent). A series of diverse ethylzinc pyrazolates and indazolates were identified using advanced NMR spectroscopy and the single crystal X-ray diffraction techniques. The NMR experiments indicate that dimeric moieties of the general formula [EtZn(pz)](2) or [Et2Zn2(pz)(2)(THF)] are favoured in solution. Nevertheless, these types of complexes are kinetically labile and tend to undergo ligand scrambling reactions according to the Schlenk equilibrium. For example, the alkyl substituents in the pz(Me2) and pz(iPr2) ligands do not appear to be a strong determinant of the dimeric moieties and the composition of the isolated complexes by crystallisation from the parent reaction mixture varies between spiro-type tri- and tetranuclear aggregates, [Et2Zn3(pz)(4)(THF)(x)] (x = 0 or 2) and [Et2Zn4(pz)(6)(THF)(2)], respectively. The nonstoichiometric formula of these organozinc derivatives is likely related to both the Schlenk-type equilibria and solubility of the respective moieties. In turn, the high steric demands of the 3,5-di-tert-butylpyrazolate ligand promote the dimeric form in solution and the solid state. Interestingly, the ethylzinc indazolate complex also does not undergo a redistribution reaction and yields a dimer.

Strategies for altering the reaction pathway of reactive intermediates are of significant importance in diversifying organic synthesis. Enol silyl ethers, versatile enolate equivalents, are known to undergo one-electron oxidation to generate the radical cations that spontaneously form electrophilic alpha-carbonyl radicals via elimination of the silyl groups. Here, we demonstrate that close scrutiny of the property of the radical cations as strong C-H acids enables the identification of a catalyst system consisting of an iridium-based photosensitizer and 2,4,6-collidine for the generation of nucleophilic allylic radicals from enol silyl ethers through one-electron oxidation-deprotonation sequence under light irradiation without the desilylation of the radical cation intermediates. The resultant allylic radicals engage in the addition to electron-deficient olefins, establishing the selective allylic C-H alkylation of enol silyl ethers. This strategy is broadly applicable, and the alkylated enol silyl ethers can be transformed into highly functionalized carbonyl compounds by exploiting their common polar reactivity.
