New insight is provided into the chemistry of 12 para-substituted nitrobenzene compounds, using the high-level computational method G3(MP2) and DFT methods. The results show that the chemical properties of the nitrobenzene molecules, such as reduction potential, ionization energy, proton affinity, pK(a), interaction energy of the fragments, hyperpolarizability, exaltation index, band gap, UV electron excitation, and QTAIM properties, are controlled by the strong coupling between the nitro group (NO2) and the nature of the various para-substituents via the benzene ring as their conducting link. As the electron donating tendency of the para-substituent increases in the molecules, the electron cloud around the nitro group also increases, resulting in contraction of the N-C bonds and elongation of the N=O bonds, consequently leading to gradually increasing electron conductivity, polarizability, and ionization energy but lower proton affinity, thereby progressively impeding the reduction potential of the molecules. The experimental reduction potential was reproduced to a high degree of accuracy, with a mean absolute deviation (MAD) of 0.048V, depending on the computational method used and the choice of the free energy circle. Additionally, the experimental electron affinity and proton affinity of the 12 molecules were reproduced to a high degree of accuracy.

An iridium-catalyzed transfer hydrogenation of N-heteroarenes to access a series of substituted 1,2,3,4-tetrahydroquinoline derivatives in excellent yields is disclosed. This transformation is distinguished with water-soluble and air-stable iridium complexes as the catalyst, formic acid as the hydrogen source, mild reaction conditions, and broad functional group compatibility. Most importantly, a tentative chiral N,N-chelated Cp*Ir(III) complex-catalyzed enantioselective transfer hydrogenation is also presented, affording chiral products in excellent yields and good enantioselectivities.

Designing and fabricating catalysts with highly dispersed metal nanoclusters (NCs) is very crucial for achieving high activity and selectivity. In this work, all-alkynyl-protected [Ag-74(C CPh)(44)](NO3)(2) cluster (Ag duster) with a well-defined structure was firstly intercalated in alpha-zirconium phosphate (alpha-ZrP) through ion-exchange. Then the atomically precise Ag cluster can be immobilized robustly in the support by a sequential process of carbonization, calcination and reduction. The supported Ag duster showed the relatively high catalytic activity (TOP = 222.9-445.8 h(-1)) and excellent recyclability for hydrogenation of a variety of nitroaromatics, as well as the compounds with carbon-carbon double bonds even if the loading of Ag was as low as 0.72 wt.%. Zirconium pyrophosphate acts as not only a stabilizer of Ag duster through a spatial confinement, but also an adsorption site for nitroaromatics. The residual carbon arisen from thermal decomposition of all-alkynyl ligand coordinating on Ag cluster exerted an important role in protecting Ag duster from sintering. As a result, the intercalation of Ag cluster in the interlayer region is a promising strategy for extending their potential applications in catalysis.

A titanium.IV) oxide photocatalyst modified with 2,3-dihydroxynaphthalene (DHN/TiO2) responds to visible light, and electrons are photogenerated to the conduction band of TiO2 under light irradiation in the presence of a suitable hole scavenger. The reducing potential of DHN/TiO2 was applied for photocatalytic conversion of a nitro group to an amino group of aromatics having other reducible groups under hydrogenfree and noble metal-free conditions at room temperature. Various nitro aromatics having vinyl, chloro, bromo, and acetyl groups were converted to amino aromatics with high yields with the reducible groups being preserved. Some parameters affecting the catalytic performance were investigated, and the reaction rate was almost determined by the amount of the substrate adsorbed on DHN/TiO2.

On water catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3’s C-13 NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.

The crystal structures of seven alpha-aryl-alpha-hydroxyphosphonates synthesized by the Pudovik reaction of substituted benzaldehydes and dialkyl phosphites, namely dimethyl [(hydroxy)(phenyl)methyl] phosphonate, C9H13O4P, dimethyl [(3,4-dimethoxyphenyl)(hydroxy)methyl]phosphonate, C11H17O6P, dimethyl (1-hydroxy-1-phenylethyl) phosphonate, C10H15O4P, dimethyl [1-hydroxy-1-(4-nitrophenyl)ethyl]phosphonate, C10H14NO6P, dibenzyl [hydroxy(2-nitrophenyl)methyl]phosphonate, C21H20NO6P, dibenzyl [(3-chlorophenyl)(hydroxy)methyl]phosphonate, C21H20ClO4P, and dibenzyl [hydroxy(4-methylphenyl)methyl]phosphonate, C22H23O4P, were studied to gain a better understanding of the organization in this type of molecule in the solid state. The crystals obtained for this series of compounds show a balance between C-OH center dot center dot center dot O-P chain-linked packing and the dimeric types of hydrogen-bond bridges of intermolecular pairs of such functions. The description is based on primary graph-set descriptors. Using graph-set descriptors one level deeper (i.e. secondary graph sets of the C-H center dot center dot center dot O type) revealed a similarity in the graph-set descriptors, suggesting a fine interplay of substituent- and shape-dependent effects on strong-weak interactions. It seems that the formation of chains or dimers is governed not only by the presence of a tertiary C alpha atom, but also by the nature and crowding of the ortho substituents of the alpha-aryl group.

Carbon nanospheres, CCDs, were fabricated using beta-cyclodextrin as carbon precursor. The as prepared CCD was then hybridized with halloysite nanotubes (Hal) through hydrothermal treatment to furnish a nanocomposite, Hal-CCD that was subsequently applied as support to stabilize Pd nanoparticles. Investigation of the catalytic activity of palladated nanocomposite, Pd@Hal-CCD, for the hydrogenation reaction of nitrobenzenes confirmed that Pd@Hal-CCD could efficiently promote the hydrogenation reaction under mild reaction condition. Moreover, the catalyst was recyclable and showed slight Pd leaching upon reusing. The comparison of the catalytic activity of Pd@Hal-CCD with that of Pd@Hal and Pd@CCD indicated the superior catalytic activity of the former. The observed high catalytic activity of the catalyst was attributed to its higher Pd loading and water disperse ability. Additionally, the results confirmed that the ratio of Hal:CCD could affect the catalytic activity and the best result was obtained by using Hal:CCD ratio of 1:2. (C) 2019 Elsevier Ltd.

The use of ubiquities elements such as iron instead of expensive precious metals as catalysts is one goal toward realizing environmentally benign synthetic chemistry. Here, we report that porous FeO(OH) dispersed on Mg-Al hydrotalcite acts as a bifunctional heterogeneous catalyst in the one-pot synthesis of 2-substituted quinoline derivatives through dehydrogenative oxidation-cyclization reactions. The catalyst was prepared by a simple grafting method using FeCl3 and Mg-Al hydrotalcite. The prepared porous FeO(OH) possesses a higher surface area than those previously reported for alpha-FeO(OH) particles. The one-pot quinoline synthesis proceeded effectively under non-noble-metal catalysis in air without requiring additional homogeneous bases or solvents.

A synergistic gold-iron (Au-Fe) catalytic system was developed for sequential alkyne hydration and vinyl Au addition to aldehydes or ketones. Fe(acac)(3) was identified as an essential co-catalyst in preventing vinyl Au protodeauration and facilitating nucleophilic additions. Effective C-C bond formation was achieved under mild conditions (room temperature) with excellent regioselectivity and high efficiency (1% [Au], up to 95% yields). The intramolecular reaction was also achieved, giving successful macrocyclization (16-31 ring sizes) with excellent yields (up to 90%, gram scale) without extended dilution (0.2 M), which highlights the great potential of this new crossed aldol strategy in challenging target molecule synthesis.
