The selective hydrogenation of nitro compounds into their corresponding azo compounds is challenging in organic synthesis. In this study, we have developed a facile and efficient catalytic system for the transformation of nitro compounds into azo compounds under mild conditions over a heterogeneous cobalt catalyst (Co-N-x/C-800-AT). The Co-N-x/C-800-AT catalyst was found to be highly active for the reductive-coupling of nitro compounds into azo compounds in ethanol at 110 degrees C and 2.5 bar H-2 pressure with the addition of NaOH as an additive, affording structurally-diverse azo compounds with satisfactory yields (70.4-98.3%). The developed method demonstrated several advantages such as high catalytic activity and high selectivity with tolerance to other functional groups and high stability.

A convenient access toward novel fluoroionophores based on 1-(2-pyridyl)-4-styrylpyrazoles (PSPs) substituted at position 3 with donor or acceptor aryl groups is reported. The synthesis proceeds in two steps: the first one via Wittig olefination of the appropriate 4-formylpyrazole and then Mizoroki-Heck coupling to yield the desired products in an overall yield of up to 69%. Photophysical properties of products (4-styryl) and their intermediates (4-vinyl) were explored, finding that they have strong blue-light emission with high quantum yields (up to 66%) due to ICT phenomena. The 3-phenyl PSP was studied as a turn-off fluorescent probe in metal ion sensing, finding a high selectivity to Hg2+ (LOD = 3.1 x 10(-7)M) in a process that could be reversed with ethylenediamine. The sensing mechanism and binding mode of the ligand to Hg2+ were established by HRMS analysis and H-1 NMR titration tests.

Asymmetric catalysis with readily available, cheap, and non-toxic alkaline earth metal catalysts represents a sustainable alternative to conventional synthesis methodologies. In this context, we describe the development of a first Mg-II-catalyzed enantioselective hydroboration providing the products with excellent yields and enantioselectivities. NMR spectroscopy studies and DFT calculations provide insights into the reaction mechanism and the origin of the enantioselectivity which can be explained by a metal-ligand cooperative catalysis pathway involving a non-innocent ligand.

Zinc linked amino acid complex, Zn(l-proline)(2), is considered as a green catalyst for the synthesis of novel series of pyrimidine derivatives 5a-q. The pyrimidines 5a-q were prepared via two pathways: the first is a one-pot reaction of guanidines 3(a-c) with aromatic aldehyde 1 and acetophenones 2; and the second one is the reaction of guanidines 3(a-c) with different chalcones 4(a-j) in aqueous medium. The simplicity of the operation, the short reaction time, and the high efficiency (97%) are the main advantages of this protocol. Furthermore, the green aspects of this synthetic protocol were further investigated by examining the reusability of Zn(l-proline)(2) complex throughout five consecutive cycles without a significant loss of catalytic activity. This new procedure has presented remarkable advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and high purities without using any organic solvents.

Substituted arylethylamines represent a key structural motif in natural, pharmaceutical, and agrochemical compounds. Access to such scaffolds has been the subject of long-standing synthetic interest. Herein, we report the synthesis of such scaffolds via a palladium-catalyzed C(sp(3))-C(sp(3)) coupling between (chloromethyl)aryls and air-/moisture-stable N,N-dialkylaminomethyltrifluoroborate salts. Rapid hit identification was achieved using microscale high-throughput experimentation and was followed by millimolar-scale reaction parameter optimization. A range of structurally and electronically varied arylethylamine products were obtained in moderate to excellent yields (27-96%, >60 examples). The reaction mechanism is proposed to proceed via formation of a trialkylbenzylammonium species prior to oxidative addition.

Synthesis of new functional organic molecules is a critical path that may greatly accelerate the evolution of organic optoelectronic materials. We have achieved a facile synthesis strategy to produce unique saddle-shaped multi-functional triazepinium salts that exhibit excellent solid-state fluorescence. Their fluorescence performance could be easily regulated by adjusting the dihedral angle between the main skeleton and the substituted moiety, giving a large Stokes shift, non-aggregation quenching, long lifetime, and multilevel-redox characteristics.

Four triphenylpyridine diamines with different substituent structure were successfully synthesized and polymerized to obtained polyimides (PIs) via one-step. The diamines and PIs were characterized by FTIR and H-1-NMR spectra. The aggregated structure of PIs was amorphous by wide angle X-ray diffraction test. The structure of the substituent had an important influence on the properties of PI (such as solubility, thermal stability, optical and mechanical properties). The introduction of tert-butyl group could reduce the solubility in non-polar solvent of PI. In addition, the introduction of hydroxyl group alone could increase the solubility in polar solvent of polymer due to the large polarity of the hydroxyl groups. All PIs exhibited high thermal stability and heat resistance, but the introduction of too much tert-butyl group reduced the thermal stability of PI. The introduction of tert-butyl group could effectively improve the optical properties of PIs. The maximum transmittance of PIs was above 85% (87.2-90.3%).

Deuterium- and tritium-labeled compounds play a principal role in tracing of biologically active molecules in complicated biochemical systems. The state-of-the-art techniques using noble metal catalysts or strong reducing agents often suffers from low functional group tolerances, poor selectivity, tricky or multistep synthesis of reagents, and low specific activity of the labeled product. Herein, we demonstrate a mild and nonmetallic technique of deuteration and tritiation of polarized double bonds, such as carbonyl compounds, yielding labeled alcohols of high specific activities. This one-pot synthesis uses carrier-free hydrogen gas in situ activated by a freshly prepared frustrated Lewis pair, generating reducing reagents. This labeling strategy shows better selectivity and functional group tolerances compared with current reductive methods. Reported is an example of the selective reduction of the aldehyde moiety of 3-acetylbenzaldehyde. What makes this technology groundbreaking is its mildness, selectivity, and generation of limited amount of radioactive waste as almost no byproducts were generated after use of (B(C6F5)(3)H-3)((HTMP)-H-3) reducing reagent. Radiochemical purity of desired H-3-labeled product in a crude reaction mixture was determined of over 94%. This work provides, to the community of radiochemists, a practical protocol for frustrated Lewis pairs (FLP)-assisted deuterium/tritium labeling technology.
