The transition metal free reduction of aromatic/heteroaromatic nitro compounds to amines has been improved employing phenyl(2-quinolyl)methanol (PQM) as organocatalyst in the presence of NaBH(4)or NaCNBH(3)as stoichiometric reducing agent. The procedure is chemoselective for NO(2)group reduction with high tolerance of many functionalities. The reaction pathway strongly depends on the substituents present on the nitroarene ring. However, a careful choice of the reaction conditions allows to address the reduction process towards the corresponding anilines (isolated in 17-91 % yields). The use of substoichiometric amounts of PQM allows more sustainable processes: reaction products are easily isolated and PQM can be directly recovered at the end of the reaction and recycled.

I found the field of Chemistry very interesting. Saw the article Mn(III) active site in hydrotalcite efficiently catalyzes the oxidation of alkylarenes with molecular oxygen published in 2021.

Developing efficient heterogeneous catalytic systems based on easily available materials and molecular oxygen for the selective oxidation of alkylarenes is highly desirable. In the present research, NiMn hydrotalcite (Ni2Mn-LDH) has been found as an efficient catalyst in the oxidation of alkylarenes using molecular oxygen as the sole oxidant without any additive. Impressive catalytic performance, excellent stability and recyclability, broad applicable scope and practical potential for the catalytic system have been observed. Mn3+ species was proposed to be the efficient active site, and Ni2+ played an important role in stabilizing the Mn3+ species in the hydrotalcite structure. The kinetic study showed that the aerobic oxidation of diphenylmethane is a first-order reaction over Ni2Mn-LDH with the activation energy (E-a) and pre-exponential factor (A(0)) being 85.7 kJ mol(-1) and 1.8 x 109 min(-1), respectively. The Gibbs free energy (Delta G(not equal)) was determined to be -10.4 kJ mol(-1) K-1 for the oxidation based on Eyring-Polanyi equation, indicating the reaction is exergonic. The mechanism study indicated that the reaction proceeded through both radical and carbocation intermediates. The two species were then trapped by molecular oxygen and H2O or hydroxyl species, respectively, to yield the corresponding products. The present research might provide information for constructing highly efficient and stable active site for the catalytic aerobic oxidation based on available and economic material.

A strategy for heterogeneous copper(I) mesoporous silica [Cu(I)-SBA-15] mediated catalytic reduction has been developed for the reduction of various nitroarenes in excellent yields. In addition to alcothermal strategy, other strategies have been attempted for the preparation of Cu(I) substituted mesoporous silica, however, the desired oxidation state is obtained only through alcothermal strategy. The crystalline phases and oxidation state of synthesized materials were characterized by XRD and XPS measurements and tested for catalytic reduction of nitroarenes. Among the tested materials, the best catalytic reduction of nitroarenes with an excellent substrate scope and good catalytic reusability was established by Cu(I)-SBA-15 material. The reduction kinetics and the controlled experimental studies reveal that the reaction proceeds through pseudo-first-order kinetics and nitrosobenzene intermediate pathway.

Heteroatom-doped porous carbon materials have exhibited promising applications in various fields. In this work, sulfur, nitrogen co-doped carbon materials (SNCs) with abundant pore structure were prepared by pyrolysis of sulfur, nitrogen-containing porous organic polymers (POPs) mixed with nano-CaCO3 at high temperature. Among the resultant materials, SNC-Ca-850 possesses a relatively high level of doped heteroatoms and exhibits an excellent catalytic performance for the selective oxidation of benzylic C-H bonds. It is noteworthy that nano-CaCO3 increases the doped sulfur content in the synthesized carbon materials to a large extent and impacts the existence modes of sulfur. In addition, it enhances the porous structure and specific surface area of the resultant SNCs significantly. This work provides a viable strategy to promote the doping of sulfur into carbon materials during the pyrolysis process.

Catalytic hydrogenation of nitroaromatics is an environment-benign strategy to produce industrially important aniline intermediates. Herein, we report that Fe(OH)(x) deposition on Pt nanocrystals to give Fe(OH)(x)/Pt, enables the selective hydrogenation of nitro groups into amino groups without hydrogenating other functional groups on the aromatic ring. The unique catalytic behavior is identified to be associated with the Fe-III-OH-Pt interfaces. While H-2 activation occurs on exposed Pt atoms to ensure the high activity, the high selectivity towards the production of substituted aniline originates from the Fe-III-OH-Pt interfaces. In situ IR, X-ray photoelectron spectroscopy (XPS), and isotope effect studies reveal that the Fe3+/Fe2+ redox couple facilitates the hydrodeoxygenation of the -NO2 group during hydrogenation catalysis. Benefitting from Fe-III-OH-Pt interfaces, the Fe(OH)(x)/Pt catalysts exhibit high catalytic performance towards a broad range of substituted nitroarenes.

Described is a physical organic study of the reduction of three sets of carbonyl compounds by the NADPH-dependent enzyme Clostridium acetobutylicum alcohol dehydrogenase (CaADH). Previous studies in our group have shown this enzyme to display broad substrate promiscuity, yet remarkable stereochemical fidelity, in the reduction of carbonyl compounds, including alpha-, beta- and gamma-keto esters ( d -stereochemistry), as well as alpha,alpha-difluorinated-beta-keto phosphonate esters ( l -stereochemistry). To better mechanistically characterize this promising dehydrogenase enzyme, we report here the results of a Hammett linear free-energy relationship (LFER) study across three distinct classes of carbonyl substrates; namely aryl aldehydes, aryl beta-keto esters and aryl trifluoromethyl ketones. Rates are measured by monitoring the decrease in NADPH fluorescence at 460 nm with time across a range of substrate concentrations for each member of each carbonyl compound class. The resulting v (0) versus [S] data are subjected to least-squares hyperbolic fitting to the Michaelis-Menton equation. Hammett plots of log( V (max) ) versus sigma (X) yield the following Hammett parameters: (i) for p -substituted aldehydes, rho = 0.99 +/- 0.10, rho = 0.40 +/- 0.09; two domains observed, (ii) for p -substituted beta-keto esters rho = 1.02 +/- 0.31, and (iii) for p -substituted aryl trifluoromethyl ketones rho = -0.97 +/- 0.12. The positive sign of rho indicated for the first two compound classes suggests that the hydride transfer from the nicotinamide cofactor is at least partially rate-limiting, whereas the negative sign of rho for the aryl trifluoromethyl ketone class suggests that dehydration of the ketone hydrate may be rate-limiting for this compound class. Consistent with this notion, examination of the (13) C NMR spectra for the set of p -substituted aryl trifluo-romethyl ketones in 2% aqueous DMSO reveals significant formation of the hydrate ( gem -diol) for this compound family, with compounds bearing the more electron-withdrawing groups showing greater degrees of hydration. This work also presents the first examples of the CaADH-mediated reduction of aryl trifluoromethyl ketones, and chiral HPLC analysis indicates that the parent compound alpha,alpha,alpha-trifluoroacetophenone is enzymatically reduced in 99% ee and 95% yield, providing the ( S )-stereoisomer, suggesting yet another compound class for which this enzyme displays high enantioselectivity.
