This study evaluated the effect of different sugar smoking times on the flavour profiles of chicken drumsticks using an electronic nose (E-nose), electronic tongue (E-tongue), and headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME/GC-MS). The moisture content, water activity, pH, and L*-value decreased from 71.26% to 65.23%, 0.987 to 0.979, 6.66 to 5.36, and 61.84 to 52.34, respectively (P < 0.05). The a*-value and b*-value increased from 4.96 to 9.65 and 16.61 to 26.45, respectively (P < 0.05) with the increase in smoking times. Seventy-five volatile compounds were identified, and 18 volatile compounds were identified as key odour compounds and among them seven key volatile compounds with variable importance in projection (VIP) > 1 were detected. Principal component analysis of E-nose, E-tongue, and HS-SPME/GC-MS indicated that 3-, 4-, and 5-min smoking samples had similar odour and taste profiles. Sensory analysis indicated that the 4-min sample had increased overall acceptability. The correlation analysis of E-nose and key volatile compounds with odour activity value > 1 and VIP >1 confirmed that W1C, W3C, and W5C sensors were sensitive to aromatic compounds, and W2S sensor was sensitive to ketones. These results may provide guidance for smoked chicken producers to reasonably control flavour formation.

A redox-active iminoquinone motif connected with pi-delocalized pyrene core has been reported that can perform efficient two-electron oxidation of a class of substrates. The design of the molecule was inspired by the organic redox cofactor topaquinone (TPQ), which executes amine oxidation in the enzyme, copper amine oxidase. Easy oxidation of both primary and secondary alcohols happened in the presence of catalytic KOtBu, which could reduce the ligand backbone to its iminosemiquinonate form under photoinduced conditions. Moreover, this easy oxidation of alcohols under aerobic condition could be elegantly extended to multi-component, one-pot coupling for the synthesis of quinoline and pyrimidine. This organocatalytic approach is very mild (70 degrees C, 8 h) compared to a multitude of transition-metal catalysts that have been used to prepare these heterocycles. A detailed mechanistic study proves the intermediacy of the iminosemiquinonate-type radical and a critical hydrogen atom transfer step to be involved in the dehydrogenation reaction.

Graphitic carbon nitride (g-C3N4, CN for short) is a compelling visible-light responsive photocatalyst. However, its photocatalytic efficiency is low due to the random carrier transfer in planes and insufficient redox potential. Herein, we build oxygen functional group modified sodium-doped carbon nitride (OH/Na co-functionalized carbon nitride) to promote directional transfer of charge carriers for acceleration of separation and enhance redox potential for efficient oxidation of NO in air. Specifically, the function of sodium atoms could control the directional transfer of random carriers from the intralayer to the oxygen functional group-modified surface for the purpose of effectively reducing photogenerated electron-hole recombination. Meanwhile, the modification by oxygen-containing functional groups could adjust the band structure of CN, thereby increasing the oxidation-reduction potential of NO in the photocatalyst. The transformation pathways and reaction mechanism of photocatalytic NO oxidation on CN and OH/Na co-functionalized carbon nitride have also been explicated by ESR spectroscopy and in situ DRIFTS and compared. This work provides a new method for simultaneously controlling the random transfer of carriers and adjusting the energy band structure of CN to optimize its photocatalytic efficiency. It is also possible to extend this strategy to improve the performance of other 2D layered catalysts for photocatalytic oxidation.

The oxidation of aldehydes is an efficient methodology for the synthesis of carboxylic acids. Herein we hope to report a simple, efficient and recyclable protocol for aerobic oxidation of aldehydes to carboxylic acid by using C3N4 supported silver nanoparticles (Ag/C3N4) as a catalyst in aqueous solution under mild conditions. Under standard conditions, the corresponding carboxylic acids can be obtained in good to excellent yields. In addition, Ag/C3N4 is convenient for recovery and could be reused three times with satisfactory yields.

Industrial-scale synthesis of eldecalcitol is described. AA highly diastereoselective epoxidation of p-methoxybenzyl (PMB) protected dienol at room temperature provides the key epoxide intermediate with a secondary hydroxyl group, which is alkylated with a triflate to set up all of the subunits at the C-1, C-2, and C-3 positions of the A-ring fragment. Selective protecting group manipulation followed by palladium-catalyzed cyclization then provides the A-ring synthon. The C/D-ring fragment is obtained by (1) direct C-H hydroxylation of Grundman’s ketone using in situ prepared trifluoropropanone dioxirane and (2) protection. Finally, the coupling of the A-ring with the C/D-ring fragment, global deprotection, and recrystallization provide the highly crystalline eldecalcitol.

In this study, we present a versatile and easy procedure for modifying a cobalt ferrite nanoparticle step by step. A new nanocatalyst was prepared via Cu(II)immobilized onto CoFe2O4@HT@Imine. The catalyst was fully characterized by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) analyses. The current procedure as a green protocol offers benefits including a simple operational method, an excellent yield of products, mild reaction conditions, minimum chemical wastes, and short reaction times. Without any significant reduction in the catalytic performance, up to five recyclability cycles of the catalyst were obtained. The optimization results suggest that the best condition in the oxidation of benzyl alcohol derivatives is 0.003 g of the CoFe2O4@HT@Imine-Cu(II)catalyst, TEMPO, at 70 degrees C under solvent-free condition and air.

In the present work, twenty-four environmentally-sensitive cyanopyridine fluorophores bearing pyrene and/ or fluorene with different para-substituted-phenyl moieties that have been previously designed and synthesized by us are studied in depth for their photophysical properties. Initially, the optical performances of the compounds were investigated by employing UV-visible and fluorescence spectroscopic tools in various aprotic and protic solvents. All the compounds exhibited absorption bands between 310 and 452 nm, and emission bands between 454 and 633 nm. High sensitivity emission spectra with solvents of different polarities were recorded and studied. The fluorescence quantum yield (phi(f)) increased in solvents of low polarity and decreased on increasing the polarity of solvents. On the other hand, in case of strong electron donating (-NMe2) and strong electron attracting (-CN) substitution, a pronounced increase in Stokes shifts (up to 252 nm, 14250 cm(-1)) were recorded. Lippert-Mataga and Reichardts correlations, applied for estimating the variation in dipole moments (Delta mu), suggested that the emissive state of designed fluorescence 3-cyanopyridine derivatives is of strong ICT character. The aprotic and protic solvents gave a linear plot for the Stokes shifts in a Lippert-Mataga plot, which appeared as two distinct domains in E-T(30) scales indicating the presence of hydrogen bondings. It was observed that for compounds 5b – 8b, with (-NMe2) group on the skeleton of phenyl ring, the Lippert-Mataga and Reichardt-Dimroth’s plots deviated from linearity signifying that 5b – 8b molecules were involved in specific interaction with protic solvents.

Combining the encapsulating capability of cyclodextrin and instinctive features of bentonite clay, a versatile metal free catalyst has been developed that could promote various chemical reactions such as Knoevenagel condensation, synthesis of xanthan and octahydroquinazolinones in aqueous media under ultrasonic irradiation. To prepare the catalyst, bentonite was Cl-functionalized and then reacted with isatin and guanidine successively to furnish amino functionalized bentonite. The latter then reacted with tosylated cyclodextrin. The resultant catalytic composite was characterized via XRD, SEM, EDS, BET, elemental mapping analysis, TGA and FTIR. The catalytic activity tests approved excellent activity of the catalyst as well as broad substrate scope. Notably, the catalyst could be simply recovered and reused for several reaction runs. Moreover, the activity of the composite was superior to that of its components.
