Two cis-1,2-diol-type chiral ligands (T-1 and T-2) and their tri-coordinated chiral dioxaborinane (T(1-2)B(1-2)) and four-coordinated chiral dioxaborinane adducts with 4-tert-butyl pyridine sustained by N -> B dative bonds (T(1-2)B(1-2)-N) were synthesized and characterized by various spectroscopic techniques such as NMR (H-1, C-13, and B-11), FT-IR and UV-Vis spectroscopy, LC-MS/MS, and elemental analysis. It was suggested that both ferrocene and trifluoromethyl groups played key roles in the catalytic and biological studies because they could tune the solubility of the chiral dioxaborinane complexes and adjust the strength of intermolecular interactions. To assess the biological activities of newly synthesized chiral dioxaborinane compounds, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging, reducing power, antibacterial, DNA binding, and DNA cleavage activities were tested. Then, all chiral dioxaborinane complexes were investigated as catalysts for the asymmetric transfer hydrogenation of various ketones under suitable conditions. The results indicated that the chiral dioxaborinane catalysts performed well with high yields.

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

The ketones was successfully prepared from secondary alcohols using 9-azabicyclo[3.3.1]nonane-N-oxyl (ABNO) as the catalyst and 2,6-lutidine as the base in acetonitrile solution. The electrochemical activity of ABNO for oxidation of 1-phenylethanol was investigated by cyclic voltammetry, in situ Fourier transform infrared spectroscopy (FTIR) and constant current electrolysis experiments. The resulting cyclic voltammetry indicated that ABNO exhibited much higher electrochemical activity when compared with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) under the similar conditions. A reasonable reaction mechanism of the electrocatalytic oxidation of 1-phenylethanol to acetophenone was proposed. In addition, a series of secondary alcohols could be converted to the corresponding ketones at room temperature in 80-95% isolated yields.

The first general palladium-catalyzed alpha-arylation of arylacetonitriles with aryl and heteroaryl sulfonates are reported. Pd(OAc)(2) associated with XPhos serves as the effective catalyst to facilitate this reaction. A broad range of electron-rich, -neutral, -deficient, and sterically hindered aryl/heteroaryl tosylates and mesylates are coupled with arylacetonitriles bearing different substituents to give the corresponding products in good to excellent yields. Catalyst loading down to 0.1 mol-% Pd was achieved, and 22 unprecedented compounds were synthesized from 43 demonstrated examples using this method. Its applicability with the modification of biological phenolic compounds was successfully demonstrated. The Pd/XPhos system catalyzed the alpha-arylation and followed by alkylation in one-pot sequential conditions, resulting in the direct synthesis of compounds containing quaternary center- and deuterium-containing compounds in good to excellent yields.

Acetic acid mediated regioselective synthesis of novel 2,4,5- trisubstituted thiazole derivatives has been reported by a domino reaction of thiosemicarbazide and aldehydes/ ketones/ isatin, to generate thiosemicarbazones ( in situ) followed by addition of arylglyoxal and active methylene/ activated C- H acids/ pyrazole/ indole in ethanol at 80 1C. The products are obtained in high yields by a simple work up. Metal free, short reaction time and high yields are some merits of this methodology.

The synthesis of calcium complexes ligated by three different chiral iminophosphonamide ligands, L-H (L=[Ph2P{N(R)CH(CH3)Ph}(2)]), L ‘-H (L ‘=[Ph2P{NDipp}{N(R)CH(CH3)Ph}]), (Dipp=2,6-(Pr2C6H3)-Pr-i), and L ”-H (L ”=[Ph2P{N(R)CH(CH3)naph}(2)]), (naph=naphthyl) is presented. The resulting structures [L2Ca], [L ‘ Ca-2], and [L ” Ca-2] represent the first examples of enantiopure homoleptic calcium complexes based on this type of ligands. The calcium complexes show blue-green photoluminescence (PL) in the solid state, which is especially bright at low temperatures. Whereas the emission of [L ” Ca-2] is assigned to the fluorescence of naphthyl groups, the PL of [L2Ca] and [L ‘ Ca-2] is contributed by long-lived phosphorescence and thermally activated delayed fluorescence (TADF), with a strong variation of the PL lifetimes over the temperature range of 5-295 K. Furthermore, an excellent catalytic activity was found for these complexes in hydroboration of ketones at room temperature, although no enantioselectivity was achieved.

The reaction of LH [L = {(ArNH)(ArN)-C=N-C=(NAr)(NHAr)}; Ar =2,6-Et-2-C6H3] with a commercially available alane amine adduct (H3Al center dot NMe2Et) in toluene resulted in the formation of a conjugated bis-guanidinate (CBG)-supported aluminum dihydride complex, i.e., LAIH(2) (1), in good yield. The new complex has been thoroughly characterized by multinuclear magnetic resonance, IR, mass, and elemental analyses, including single-crystal structural studies. Further, we have demonstrated the aluminum-catalyzed hydroboration of a variety of nitriles and alkynes. Moreover, aluminum-catalyzed hydroboration is expanded to more challenging substrates such as alkene, pyridine, imine, carbodiimide, and isocyanides. More importantly, we have shown that the aluminum dihydride catalyzed both intra- and intermolecular chemoselective hydroboration of nitriles and alkynes over other reducible functionalities for the first time.

Nonaqueous organic redox flow batteries (NAORFBs) show great promise for grid energy storage but are currently facing key challenges such as high electroactive material cost and low energy density. Herein, we report the electrochemical properties and the potential application of a series of cost-effective electroactive nitrobenzene molecules in NAORFBs. Pairing the low-cost miscible liquid nitrobenzene (NB) with 2,5-di-tert-butyl-1-methoxy-4-(20-methoxyethoxy)-benzene (DBMMB) resulted in a flow battery that provides a high theoretical cell voltage of 2.2 V and a calculated energy density of 192 Wh L-1. In the charge-discharge testing, this battery delivers a stable cycling capacity retention of 99.5% per cycle over 100 cycles and a 70% energy efficiency at 40 mA cm(-2) operation current density, verifying that liquid nitrobenzene is a promising low-cost electroactive anode molecule for NAORFBs.

A copper-catalyzed approach for the N-acylation of anilines with acetone and acetophenones via C-C bond cleavage is described. Under the developed conditions both CHCl3 and CH2Cl2 were identified as potential C1-source to promote the transformation. The reaction features a site selective C-C bond cleavage to install the amide moieties with high functional-group compatibility and wide substrate scope. The developed method avoids the use of sensitive and narcotic agents. The method also represents an excellent complement to the previous protocols with lower E-factor (13.91 mg/1 mg) than current industrially used method (E-factor 17.54 mg/1 mg). The developed approach has also been extended for the effective preparation of pyridine derivatives and paracetamol in gram scale. The course of the reaction was monitored by H-1 NMR as a preliminary investigation of the reaction mechanism.
