Presently, developing efficient and stable structured heterogenous catalysts with fabulous advantages of excellent ability for heat/mass transfer, facile recovery and separation, and superior stability is of great importance in terms of economic production of chemicals. Here, structured Cu-based film catalysts with novel surface superstructure composed of large quantities of interlaced and nearly vertically grown nanosheets for aqueousphase hydrogenation of furfural toward the production of furfuryl alcohol (FOL) and cyclopentanone (CPO) were successfully fabricated from structured Cu-Zn-Al layered double hydroxide (CuZnAl-LDH) film precursors. As-fabricated structured Cu-based film catalyst possessing a Cu/(Zn + Cu) molar ratio of 4:5 exhibited a superior catalytic performance in the above reaction to other Zn-free and Zn-rich Cu-based film catalysts, as well as pristine CuZnAl-LDH-derived powdered one, due to the synergistic effect between highly dispersive Cu species and favorable surface acidic sites originating from LDH-derived Zn-Al mixed metal oxide (ZnAl-MMO), as well as the presence of abundant Cu-MMO interface within surface nanosheets, being responsible for the enhanced adsorption and activation of reactant and reaction intermediates. Furthermore, due to strong interactions between Cu species and MMO matrix within nanosheets and between surface nanosheets and anodic aluminum oxide/aluminum substrate, the present structured catalyst showed high structural stability and reusability.

Biomass burning emits large amounts of phenols, which can partition into cloud/fog drops and aerosol liquid water (ALW) and react to form aqueous secondary organic aerosol (aqSOA). Triplet excited states of organic compounds (C-3*) are likely oxidants, but there are no rate constants with highly substituted phenols that have high Henry’s law constants (K-H) and are likely important in ALW. To address this gap, we investigated the kinetics of six highly substituted phenols with the triplet excited state of 3,4-dimethoxybenzaldehyde. Second-order rate constants at pH 2 are all fast, (2.6-4.6) x 10(9) M-1 s(-1), while values at pH 5 are 2-5 times smaller. Rate constants are reasonably described by a quantitative structure-activity relationship with phenol oxidation potentials, allowing rate constants of other phenols to be predicted. Triplet-phenol kinetics are unaffected by ammonium sulfate, sodium chloride, galactose (a biomass-burning sugar), or Fe(III). In contrast, ammonium nitrate increases the rate of phenol loss by making hydroxyl radicals, while Cu(II) inhibits phenol decay. Mass yields of aqueous SOA from triplet reactions are large and range from 59 to 99%. Calculations using our data along with previous oxidant measurements indicate that phenols with high KH can be an important source of aqSOA in ALW, with 3C* typically the dominant oxidant.

The solvent free oxidation of benzyl alcohol to Benzaldehyde using bimetallic alloy nanoparticles supported over magnesia is a benign and improved frontier in catalysis. Benzaldehyde is an important industrial feed stock of immense significance in plastic, fine and chemical industries. In this study 1% Au:Pd NPs was synthesized using sol immobilization method over different magnesia (MgO) supports. The composite nanoalloys were characterized using Nitrogen adsorption BET, X- ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The efficacy of Pd:Au/MgO, as a basic solid catalyst, has been tested for benzyl alcohol oxidation. The synthesized composite catalyst Pd:Au/MgO-4 showed high initial activity for freshly prepared catalysts with remarkable activity. This activity declined rapidly with number of runs, which could result from sintering of the support, agglomeration and leaching of active phase. Furthermore, MgO-3 exhibits good stability after 2nd runs, while MgO-5 and MgO-2 revealed marked increasing in activity after the 2nd runs due surface modification and exposure of active sites during reaction.

Herein, a dual nickel/ruthenium strategy is developed for photoinduced decarboxylative cross-coupling between alpha,beta-unsaturated carboxylic acids and cycloketone oxime esters. The reaction mechanism is distinct from previous photoinduced decarboxylation of alpha,beta-unsaturated carboxylic acids. This reaction might proceed through a nickelacyclopropane intermediate. The C(sp(2))-C(sp(3)) bond constructed by the aforementioned reaction provides an efficient approach to obtaining various cyanoalkyl alkenes, which are synthetically valuable organic skeletons in organic and medicinal chemistry, under mild reaction conditions. The protocol tolerates many critical functional groups and provides a route for the modification of complex organic molecules.

Attempted nucleophilic displacements of L-rhamnosyl 2,4-bistriflates led to serendipitous formation of a chiral diene via competing cascade eliminations. The reaction also followed the same pathway with D-rhamnosyl and Dmannosyl 2,4-bistriflates substrates providing access to dienes with opposite stereochemistry. The reaction presumably proceeds through E2 elimination of C2 triflate followed by allylic rearrangement. The easily accessible chiral dienes would be useful in the synthesis of natural products.

Herein, we report a simple and efficient approach to synthesize a functionalized 2,18-dimethoxy-5,10,15-trioxa[9]helicene. It was synthesized from simple phenol building blocks using two subsequent reactions namely oxidative coupling and dehydrative cyclization or palladium mediated cyclization. The molecular integrity of the helical core was determined by single-crystal X-ray diffraction and NMR techniques. Its crystal structure showed the spontaneous resolution which was attributed to the conglomerate formation of the same helical isomer via C-H…O and pi…pi or H…pi interactions. Then, it was converted to racemic 2,18-dihydoxy-5,10,15-trioxa[9]helicene. Enantiomers were separated on preparative HPLC with high optical purity (>99 % ee). Based on electronic circular dichroism, the absolute configurations of dextrorotary and levorotatory antipodes were assigned as P and M, respectively. We also studied the absorption, emission and chiroptical behavior of these helical compounds in the solution state.

Outfitting an aza-crown ether with an organotransition-metal pendant provides a mechanism for tuning its supramolecular properties. The binding affinity can be tuned by more than 2 orders of magnitude by changing the identity of the transition metal-center, altering the overall charge of the complex, or engaging in organometallic ligand substitution reactions. High Li+ selectivity (up to 29-fold higher affinity in comparison to Na+), proton-responsive behavior, and ion pair (ditopic) binding capabilities are observed in the metallacrown ethers.

In the treatment of wastewaters contaminated with phenol and substituted phenols, an intermediate chemical step of partial oxidation is often employed to facilitate the ensuing biodegradation process. Ozonation is a candidate technique for partial oxidation of phenolics. In this study, the kinetics of ozonation reactions of 20 substituted phenols is investigated using the renowned theory of mass transfer with chemical reaction. The stirred (Lewis) cell with a flat interface is used as a model contactor. It is found that the second-order rate constants for the reactions with the chosen phenolic compounds are in the 10(4)-10(7) s(-1) range. In particular, the rate constant for ozonation of phenol is 5.06 x 10(6) M-1 s(-1). The liquid-side mass transfer coefficient is estimated by using the chemical method, and its value (k(L) = 0.052 cm s(-1)) is in line with those typical of stirred-cell reactors. This work is useful for the design, operation, and scale-up of ozonation reactors used in wastewater treatment.

This work discusses a new measurement concept that uses contactless Raman spectrometry of free radical polymerization (FRP) in a milliscale reactor. The setup is based on a multiphase system with unsteady operation due to a change in the flow direction. The objective is to develop a quasi-isothermal measurement method for the determination of reaction kinetics with high automation capability. The FRP of acrylic acid with 2,2′-azobis(2-methylpropionamidine) dihydrochloride as the initiator serves as the model reaction. The reaction order for the initiator and monomer concentrations as well as the temperature dependence is determined. On the basis of the measured rates, an estimation of the thermal behavior of the reactor can be made. The pendular slug reactor is an extension of the known measurement methods for FRP and requires only a few grams of material.

The fluoroalkylation of various nucleophilic reagents with (phenylsulfonyl)difluoromethyl (PhSO2CF2)-substituted phenanthridines was achieved to give fluorinated phenanthridine derivatives, which enables the construction of both carbon-heteroatom and carbon-carbon bonds via the substitution of the phenylsulfonyl group. Mechanistic studies indicated that these reactions proceed through a unimolecular radical nucleophilic substitution (S(RN)1) mechanism. It is worthwhile noting that in the cases of O-nucleophiles (t-BuO- and PhO-), the addition of t-BuOK/PhCHO could significantly promote the reactions, due to the in situ formation of a highly reactive electron donor species through the interaction of t-BuOK, PhCHO, and the solvent DMF, which can effectively initiate the single electron transfer process.
