Nickel(II) Complexes with Electron-Rich, Sterically Hindered PNP Pincer Ligands Enable Uncommon Modes of Ligand Dearomatization

We report the reactivity and characterization of hydride, methyl, and bromo Ni-II complexes with a new class of electron-rich and sterically hindered PNP pincer ligands, Me4PNPR (R = Pr-i, Bu-t), in which a classical metal-ligand cooperative mode of reactivity via CH2 arm deprotonation is blocked by methylation. This enables new, uncommon modes of PNP ligand dearomatization that involve reactivity in the para position of the pyridine ring. In particular, the reduction of [(Me4PNPiPr) (NiMe)-Me-II]B(Ar-F)(4) with KC8 leads to the formation of a new C-C bond via dimerization of two complexes through the para position. This reactivity stands in sharp contrast to the previously reported bromo or chloro complexes, where stable Ni-I halogen moieties are formed. Computational analysis showed a greater propensity for ligand-centered radical formation for the presumed intermediate one-electron-reduced species. UV-induced homolysis of the Ni-II-Me bond in [(Me4PNPiPr) (NiMe)-Me-II]B(Ar-F)(4) leads to the formation of a Me radical detected by radical traps and Ni(I )intermediates that can be trapped in the presence of halide ions to give previously characterized, stable Ni-I halogen complexes. In addition, treatment of the bromo complexes [(Me4PNPR)(NiBr)-Br-II]BPh4 with a powerful hydride source, LiBEt3H, leads to the reduction of the pyridine ring and the formation of Ni-II complexes with an anionic amide donor reduced pincer ligand, although aromatic Ni-II hydride complexes could also be obtained with a weaker hydride source. We have observed that steric bulk at the phosphine donors controls the reactivity of the resulting Ni(II)H( )complexes. While t-Bu-substituted [(Me4PNPtBu) (NiH)-H-II]Y(Y=BPh4, B(Ar-F)(4)) does not react with O-2, the less sterically hindered Pr-i-substituted [(Me4PNPiPr)(NiH)-H-II]Y reacts instantaneously to give an unstable superoxide adduct that can be observed by EPR.

A novel 3D-printable hydrogel with high mechanical strength and shape memory properties

The three-dimensional (3D)-printing of hydrogels with excellent mechanical properties has attracted extensive attention owing to their potential applications in many fields. Through the photoinitiated copolymerization of methacrylic acid (MAAc) and N-(pyridin-2-yl)acrylamide (NPAM) in dimethylsulfoxide (DMSO), a copolymer solution was prepared; it was then 3D printed at 70 degrees C followed by solvent replacement of DMSO with water at 25 degrees C, and a novel 3D-printed tough hydrogel was prepared. In the presence of water, NPAM could undergo multi-fold hydrogen bonding with MAAc. Thus, the hydrogen bonding is strengthened and stabilized by the hydrophobic alpha-methyl of MAAc and the pyridine N-heterocycle of NPAM, meaning that the modules of the hydrogel can be up to five times stronger than the original organogels. The swelling or shrinkage of the gel is negligible during solvent replacement and the resultant hydrogel exhibits excellent mechanical properties, with an elastic modulus of 1.8-66 MPa, a tensile fracture stress of 2.2-6.3 MPa, a fracture strain of 360-570% and a fracture energy of 0.5-7.2 kJ m(-2). In addition, owing to the dynamic nature and temperature sensitivity of the hydrogen bonds, the hydrogel also exhibited fast self-recovery abilities and temperature activated shape memory properties. In particular, the hydrogen-bonding hydrogel could be quickly degraded and recovered by adjusting the pH, which allowed convenient recycling of the hydrogels. Our experimental results indicated that the combination of a 3D-printing technique and solvent replacement may provide a novel and effective method to obtain 3D-printed hydrogels with high mechanical strength and shape recovery properties, fostering their use in a number of fields such as soft robots, implant devices, tissue engineering and other environment friendly materials.

Structural and electronic properties of layered nanoporous organic nanocrystals

In this work, we present the optimized geometric stacking of several layered nanoporous organic nanocrystals (NONs) and the stacking effect on their electronic structure. Hexagonal layered structures, C12H6-h2D, B6N6H6-h2D and C6N6-h2D are built from aromatic organic molecular units benzene, borazine and 1,3,5-triazine, respectively while oblique structures, C10N2H4-o2D, C8N4H2-o2D, C10P2H4-o2D and C10As2H4-o2D, are built from pyridine, 1,3-diazine, phosphinine and arsinine, respectively. Our density functional theory calculations show stacking energy profiles of NONs that are similar to graphene in both the stand-alone and bulk C12H6-h2D and B6N6H6-h2D structures while the rest of the studied layered materials deviate from the perfect AB stacking. The number of layers as well as the stacking configuration significantly influence the electronic properties of these materials. Indirect to direct band gap crossovers from the bulk to monolayers are observed in all of the NONs except in C6N6-h2D which exhibits a direct band gap in both the monolayer, isolated few-layers, and bulk. Furthermore, it is observed that the electronic nature of C10As2H4-o2D changes from a semiconducting character in the isolated monolayer to a metallic character in the bulk. The porous nature and the stability of these layered NONs combined with the electronic properties observed in this work point at them as valuable materials for potential applications in nanoelectronics and gas separation membranes, as well as deep ultraviolet optoelectronics and laser devices.

Hierarchical Mg/ZSM-5 catalysts for methanol-to-propylene reaction via one-step acid treatment

One-step acid treatment for template- and solvent-free synthesized NaZSM-5 was developed to obtain hierarchical HZSM-5. Hierarchical Mg/ZSM-5 was obtained by the incipient impregnation method, which further increased the propylene yield of the methanol-to-propylene (MTP) reaction. The physicochemical properties of the samples were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), N-2 adsorption-desorption, pyridine adsorption-IR (Py-IR) and NH3 temperature-programmed desorption (NH3-TPD). The results indicated that one-step acid treatment (250 degrees C, 12 h) could increase the SiO2/Al2O3 molar ratio from 29.43 to 53.33 and maintain the well-distributed state of acid sites. The blocked pore structure was opened to introduce additional mesoporosity. Additionally, NaZSM-5 was synchronously converted to HZSM-5, thereby avoiding ion-exchange procedures. Synchronization of dealumination, desodiation and introduction of the mesoporous structure was achieved in one step, providing a good matrix for further impregnation with Mg species. The obtained hierarchical Mg/ZSM-5 (0.3 M-MgO) showed low diffusion hindrance and reduction in external surface acid sites (especially Bronsted acid sites), affording high propylene selectivity (53.34%) and good resistance to carbon deposition (similar to 0.77%) in the MTP reaction.

A redox-mediated conformational change in NQO1 controls binding to microtubules and alpha-tubulin acetylation

The localization of NQO1 near acetylated microtubules has led to the hypothesis that NQO1 may work in concert with the NAD(+)-dependent deacetylase SIRT2 to regulate acetyl alpha-tubulin (K-40) levels on microtubules. NQO1 catalyzes the oxidation of NADH to NAD + and may supplement levels of NAD(+) near microtubules to aid SIRT2 deacetylase activity. While HDAC6 has been shown to regulate the majority of microtubule acetylation at K-40, SIRT2 is also known to modulate microtubule acetylation (K-40) in the perinuclear region. In this study we examined the potential roles NQO1 may play in modulating acetyl alpha-tubulin levels. Knock-out or knock-down of NQO1 or SIRT2 did not change the levels of acetyl alpha-tubulin in 16HBE human bronchial epithelial cells and 3T3-L1 fibroblasts; however, treatment with a mechanism-based inhibitor of NQO1 (MI2321) led to a short-lived temporal increase in acetyl alpha-tubulin levels in both cell lines without impacting the intracellular pools of NADH or NAD(+). Inactivation of NQO1 by MI2321 resulted in lower levels of NQO1 immunostaining on microtubules, consistent with redox-dependent changes in NQO1 conformation as evidenced by the use of redox-specific, anti-NQO1 antibodies in immunoprecipitation studies. Given the highly dynamic nature of acetylation-deacetylation reactions at alpha-tubulin K-40 and the crowded protein environment surrounding this site, disruption in the binding of NQO1 to microtubules may temporally disturb the physical interactions of enzymes responsible for maintaining the microtubule acetylome.

Green, efficient and economical coal fly ash based phosphomolybdic acid catalysts: preparation, characterization and application

Cost-effective, efficient and green solid acid catalysts have been synthesized by incipient wetness impregnation of various weight fractions of phosphomolybdic acid (5, 10, 15 and 25 wt. %) on mechanically and thermally activated coal fly ash. N-2 adsorption-desorption, XRD, FT-IR, SEM, SEM-EDX, TEM, TGA, UV-Vis DRS, solid state P-31 MAS NMR were used for characterization of as synthesized catalysts. Catalytic active sites were developed on inert surface of coal fly ash by using various activation techniques whose performance was assessed over a series of acylation of various aliphatic alcohols. For rapid and higher catalytic activity, reactions were conducted in microwave heating mode. Impregnation of phosphomolybdic acid generates Lewis acidic sites on coal fly ash surface as inferred by pyridine adsorbed FT-IR studies which were then utilized in acylation reactions. Various reaction parameters like weight fraction of catalysts, molar ratio of reactants, time, temperature, etc. were optimized for attaining highest conversion %. The catalyst with 15 wt. % of phosphomolybdic acid was found to be more efficient and could be recycled up to five reaction cycles with analogous conversion %. Negligible leaching of catalyst was confirmed by hot filtration test. This work suggests an alternative approach for valorisation of industrial solid waste, coal fly ash in development of innovative, economical solid catalysts. [GRAPHICS] .
