In this study, convenient and selective oxidation of alcohols using aqueous hydrogen peroxide to yield carbonyl compounds was studied. Using the ruthenium-(4-methylphenyl-2,6-bispydinyl) pyridinedicarboxylate complex [Ru(mpbp)(pydic)] as a catalyst, primary and secondary alcohols were oxidized to aldehydes and ketones at room temperature with a satisfactory yield and excellent selectivity. The influence of various reaction parameters, such as solvent, catalyst and oxidant amount on both the activity and selectivity was also evaluated. Kinetic studies showed that the oxidation of alcohol was first order in terms of the substrate and hydrogen peroxide, and was second order in terms of the catalyst. A plausible mechanism involving ruthenium-oxo species with electrophilic character was proposed based on the in situ UV-vis spectroscopy studies and Hammett plots.

Bifunctional catalysts comprised of both noble metal and Bronsted acid sites are of growing interest for many reactions, such as the hydrodeoxygenation (HDO) of oxygenates produced by the deconstruction of lignocellulosic biomass. One method of preparing a bifunctional metal-acid catalyst is to modify the supporting material of a metal catalyst with acid-containing ligands, such as phosphonic acids (PAs), which provide tunable Bronsted acid sites at the metal-support interface. Here, we explore the potential for PA modification to improve HDO rates on Al2O3, TiO2, CeO2, and SiO2-Al2O3 supports. PAs containing either alkyl or carboxylic acid (CA) tails were used to modify Pt catalysts on each support. PA modification improved HDO rates for the model compound benzyl alcohol when applied to Pt supported by Al2O3, TiO2, and CeO2, but had a negative effect on the HDO rate of Pt/SiO2-Al2O3. Measurements of the relative strength of Bronsted acid sites present on the modified and unmodified catalysts suggested that PAs improved HDO when they provided new or stronger Bronsted acid sites. Additionally, the strength of the Bronsted acid sites provided by PA modifiers were tunable by altering the tail functionality, which affected the rates of HDO. These results suggest that PAs can be used to modify a variety of supports to prepare bifunctional acid-metal catalysts. (C) 2019 Elsevier Inc. All rights reserved.

Coumarins and their synthetic derivatives are extensively used as base chemicals in diverse industrial applications in the fields of pharmaceutics, cosmetics, and agrochemicals, among others. Due to the growing number of applications, the need for new methods of coumarins synthesis has gained importance worldwide. In this sense, the use of propylsulfonic acid supported in FDU-5 (FDU-5-Pr-SO3H) as a catalyst for the synthesis of coumarins via Pechmann condensation in solvent free medium was investigated. FDU-5-Pr-SO3H was synthesized by co-condensation of MPTES and TEOS. FDU-5-Pr-SO3H was used as catalyst for the synthesis of 7-hydroxy-4-methylcoumarin and reaction conditions were optimized. The optimization process involved the study of the influence of the catalyst load, Resorcinol:EAA molar ratio, reaction temperature and reaction time. The optimal conditions were: catalyst load of 1.65 mol %, reactants molar ratio of 1:1.5, temperature 130 degrees C and 60 min of reaction time. Under these conditions, the FDU-5-Pr-SO3H material showed excellent yield (96.5%) and turn over frequency (59 h(-1)). Finally, the synthetized material was assessed as a catalyst with other phenolic compounds with ethyl acetoacetate and with ethyl benzoylacetate. The obtained products were isolated and identified by comparison of their spectral data with those reported in literature; from these results can be concluded that the catalyst is active with a wide range of phenolic substrates.

A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I-2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields. The broad applicability of this methodology was further highlighted by the late-stage functionalization of several phenol-containing natural products and pharmaceuticals.

This study was intended to characterize six types of commercial smoked chicken products in China by using gas chromatography-mass spectrometry (GC-MS), odor-activity values (OAVs), and sensory evaluation. Results demonstrated that a total of 89 components were identi?ed in all samples, and 34 were considered as odor-active compounds because their OAVs were greater than one. Liaocheng Chicken that smoked with fruit tree sawdust had more phenols, which contributed to the smoky aroma. Jinshan and Goubangzi Chicken that smoked with sugar had more furans which contributed the overall odor with sweety and caramel aroma. Zhuozishan and Laoting Chicken that smoked with sugar and wood chips had similar flavor and volatile compounds. Tengqiao Chicken that smoked with sugar, tea and rice had significant difference with other chicken in smoky, bittern and caramel aroma (P< .05). The diversity of these smoked chicken flavors was mainly due to the cooking culture differences.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

A new and straightforward synthesis of the C-1-C-7 core fragment of nhatrangin A was achieved in 14 steps from achiral 3-hydroxybenzaldehyde, without the need of chiral reagents or enzymatic resolution to introduce the chiral centers. The key asymmetric steps include in particular a highly enantioselective organocatalyzed Michael addition on an aryl vinyl ketone, a Sharpless asymmetric epoxidation and a subsequent regioselective ring opening of the resulting chiral epoxide. This work represents the first formal enantioselective synthesis of nhatrangin A.

Herein, we have, for the first time, fabricated a few-layered phosphorene (FLP) and few-layered carbon nitride (FLCN) nano-heterostructure as a metal-free and broad solar light-absorbing photocatalyst for highly selective conversion of primary C-H bond of toluene and benzyl alcohol to benzaldehyde in the presence of oxygen. The FLP-FLCN photocatalyst can effectively oxidize benzyl alcohol to benzaldehyde with superior selectivity (>99%) under the visible light irradiation conditions. Moreover, a conversion rate of 82.6 mmol/(g h) from toluene to benzaldehyde is achieved after 24 h of photoreaction. The fine structural analysis including synchrotron-based X-ray absorption near-edge structure and photoelectron spectroscopy and electrochemistry signifies that the enhanced photocatalytic activity of FLP-FLCN is mainly contributed from the synergistic electronic coupling at the FLP-FLCN interface. The photogenerated hole-electron pairs and superoxide anion radicals play a crucial role in facilitating the C-H oxidation reaction. In addition, the FLP-FLCN can be reused for at least five cycles to efficiently photocatalytic conversion of benzyl alcohol without obvious loss of photocatalytic activity and microstructures. These findings provide a novel strategy to synthesize a metal-free nanocatalyst for the visible-light-driven photocatalytic conversion of specific organic transformation with high selectivity and superior conversion rate.
