The TEMPO-catalyzed oxidation of alcohols to aldehydes has emerged to one of the most widely applied methodologies for such transformations. Advantages are the utilization of sodium hypochlorite, a component of household bleach, as an oxidation agent and the use of water as a co-solvent. However, a major drawback of this method is the often occurring strict limitation to use dichloromethane as an organic solvent in a biphasic reaction medium with water. Previous studies show that dichloromethane cannot easily be substituted because a decrease of selectivity or inhibition of the reaction is observed by using alternative organic solvents. Thus, up to now, only a few examples are known in which after a tedious optimization of the reaction dichloromethane could be replaced. In order to overcome the current limitations, we were interested in finding a TEMPO-oxidation method in alternative organic solvents, which is applicable for various alcohol oxidations. As a result, we found a method for N-oxyl radical-catalyzed oxidation using sodium hypochlorite as an oxidation agent in nitriles as an organic solvent component instead of dichloromethane. Besides the oxidation of aromatic primary alcohols also aliphatic primary alcohols, secondary alcohols as well as dialcohols were successfully converted when using this method, showing high selectivity towards the carbonyl compound and low amounts of the acid side-product.

Chiral, cationic NHC-iridium complexes are introduced as catalysts for the intramolecular hydroamination reaction of unactivated aminoalkenes. The catalysts show high activity in the construction of a range of 5- and 6-membered N-heterocycles, which are accessed in excellent optical purity, with various functional groups being tolerated with this system. A major deactivation pathway is presented and eliminated by using alternative reaction conditions. A detailed experimental and computational study on the reaction mechanism is performed providing valuable insights into the mode of action of the catalytic system and pointing to future modifications to be made for this catalytic platform.

The oxidation of alcohols to aldehydes or ketones is a highly relevant conversion for the pharmaceutical and fine-chemical industries, and for biomass conversion, and is commonly performed using stoichiometric amounts of highly hazardous oxidants. The aerobic oxidation of alcohols with transition metal complex catalysts previously required complicated organic ligands and/or nitroxyl radicals as co-catalysts. Herein, we report an efficient and eco-friendly method to promote the aerobic oxidation of alcohols using an inorganic-ligand supported copper catalyst 1, (NH4)(4)[CuMo6O18(OH)(6)], with O-2 (1 atm) as the sole oxidant. Catalyst 1 is synthesized directly from cheap and commonly available (NH4)(6)Mo7O24 center dot 4H(2)O and CuSO4, which consists of a pure inorganic framework built from a central Cu-II core supported by six (MoO6)-O-VI inorganic scaffolds. The copper catalyst 1 exhibits excellent selectivity and activity towards a wide range of substrates in the catalytic oxidation of alcohols, and can avoid the use of toxic oxidants, nitroxyl radicals, and potentially air/moisture sensitive and complicated organic ligands that are not commercially available. Owing to its robust inorganic framework, catalyst 1 shows good stability and reusability, and the catalytic oxidation of alcohols with catalyst 1 could be readily scaled up to gram scale with little loss of catalytic activity, demonstrating great potential of the inorganic-ligand supported Cu catalysts in catalytic chemical transformations.

Hydrazine derivatives have a wide variety of applications in organic synthesis, material science, medical treatments, as well as the dye-sensitized solar cells (DSSC). In this work, the molecular structure, electronic spectra and first principles investigation for the exo-endo isomerization in (1E,2E)-bis[1-(4-nitrophenyl)ethylidene]hydrazine were studied. The structural interactions and synthon formations have been determined experimentally via Hirshfeld surface analysis (HSA) and two-dimensional fingerprint plots (2D-FP). Furthermore, the solid-state XRD/HSA interactions have been used to explain the physical behavior of the compound. The transition state for the exo-endo isomerization was located using density functional theory (DFT). The activation barrier is estimated to be 110.5 kJ/mol (in vacuo). The endo isomer was found to be slightly more stable than the exo one. The UV-Vis spectra of the two isomers were obtained using time-dependent density functional theory (TDDFT) and compared to the experimental spectra in vacuo, water, and methanol. To explore the potential of the new compound as a DSSC sensitizer, the emission spectrum was also constructed by optimizing the singlet electronic excited state. (C) 2020 The Author(s).

We report an efficient HCl center dot DMPU assisted one-pot conversion of aldehydes into nitriles. The use of HCl center dot DMPU as both an acidic source as well as a non-nucleophilic base constitutes an environmentally mild alternative for the preparation of nitriles. Our protocol proceeds smoothly without the use of toxic reagents and metal catalysts. Diverse functionalized aromatic, aliphatic and allylic aldehydes incorporating various functional groups were successfully converted to nitriles in excellent to quantitative yields. This protocol is characterized by a broad substrate scope, mild reaction conditions, and high scalability.

Enantiopure secondary alcohols are fundamental high-value synthetic building blocks. One of the most attractive ways to get access to this compound class is the catalytic hydroboration. We describe a new concept for this reaction type that allowed for exceptional catalytic turnover numbers (up to 15 400), which were increased by around 1.5-3 orders of magnitude compared to the most active catalysts previously reported. In our concept an aprotic ammonium halide moiety cooperates with an oxophilic Lewis acid within the same catalyst molecule. Control experiments reveal that both catalytic centers are essential for the observed activity. Kinetic, spectroscopic and computational studies show that the hydride transfer is rate limiting and proceeds via a concerted mechanism, in which hydride at Boron is continuously displaced by iodide, reminiscent to an S(N)2 reaction. The catalyst, which is accessible in high yields in few steps, was found to be stable during catalysis, readily recyclable and could be reused 10 times still efficiently working.

An efficient and low-cost supported Pt catalyst for hydrogenation of niroarenes was prepared with colloid Pt precursors and alpha-Fe2O3 as a support. The catalyst with Pt content as low as 0.2 wt% exhibits high activities, chemoselectivities and stability in the hydrogenation of nitrobenzene and a variety of niroarenes. The conversion of nitrobenzene can reach 3170 mol(conv) h(-1) mol(pt)(-1) under mild conditions (30 degrees C, 5 bar), which is much higher than that of commercial Pt/C catalyst and many reported catalysts under similar reaction conditions. The spatial separation of the active sites for H-2 dissociation and hydrogenation should be responsible for the high chemoselectivity, which decreases the contact possibility between the reducible groups of nitroarenes and Pt nanoparticles. The unique surface properties of alpha-Fe2O3 play an important role in the reaction process. It provides active sites for hydrogen spillover and reactant adsorption, and ultimately completes the hydrogenation of the nitro group on the catalyst surface.

In the present work, four types of heterocyclic core-based polybenzoxazine matrices (HC-PBZ) developed based on pyridine, thiophene, and thiazole and their molecular structure, thermal, flame-retardant and luminescent properties were studied and discussed. The heterocyclic core-based benzoxazine monomers (HC-BZ) were synthesized using two types of phenols (phenol, and 4-hydroxyphenylacetonitrile), and two types of heterocyclic diamines [2,6-Bis-(4-aminophenyl)-4-thiophen-2-yl-pyridine (BATP) and 4-(2-methylthiazol-5-yl)-2,6-bis-(4-aminophenyl)-pyridine (BAMTP)] with formaldehyde through Mannich reaction. The structure of the four HC-BZ monomers was confirmed by various spectral analysis such as Fourier-transform infrared spectroscopy (FTIR), and Nuclear magnetic resonance spectroscopy ((HNMR)-H-1 and (CNMR)-C-13). All the four HC-BZ monomers have the maximum range of curing temperature (T-p) between 252 and 267 degrees C. Data resulted from the thermal studies indicate that the HC-PBZ exhibits better T-g,T- thermal stability and flame-retardant properties. Among the four HC-PBZ systems the thiazole based system possesses the higher value of T-g of 268 degrees C and thermal stability when compared to those of other matrices. It was also observed that the HC-BZ monomers and HC-PBZ polymers exhibit a photoluminescent (PL) emission range between 441-445 and 414-417nm, respectively. Overall, it seems that the thiazole and thiophene based HC-PBZ can be considered as competitive materials for luminescent applications with high thermal and flame-retardant properties.

A convenient method for the synthesis of 2-oxo-acetamidines from methyl ketones using aromatic amines and DMF as nitrogen sources is reported via copper-catalyzed C(sp(3))-H amidination. Various methyl ketones react readily with aromatic amines and DMF, producing 2-oxo-acetamidines in yields of 47 to 92%. This protocol features the simultaneous formation of C-N and C?N bonds using DMF and aromatic amines as two different nitrogen sources. It thus provides an efficient approach to construct acyclic amidines via three C(sp(3))-H bond amidination. Based on the preliminary experiments, a plausible mechanism of this transformation is disclosed.
