The silver-catalyzed hydrogenation of ketones using H-2 as hydrogen source is reported. Silver nanoparticles are generated from simple silver (I) salts and operate at 25 degrees C under 20 bar of hydrogen pressure. Various aliphatic and aromatic ketones, including natural products were reduced into the corresponding alcohols in high yields. This silver catalyst allows for the selective hydrogenation of ketones in the presence of other functional groups.

We developed an approach for direct selective hydroxylation of heterobenzylic methylenes to secondary alcohols avoiding overoxidation to ketones by using a KOBu-t/DMSO/air system. Most reactions could reach completion in several minutes to give hydroxylated products in 41-76% yields. Using DMSO-d(6), this protocol resulted in difunctionalization of heterobenzylic methylenes to afford a-deuterated secondary alcohols (>93% incorporation). By employing this method, active pharmaceutical ingredients carbinoxamine and doxylamine were synthesized in two steps in moderate yields.

The conversion of olefin feedstocks to architecturally complex alkanes represents an important strategy in the expedient generation of valuable molecules for the chemical and life sciences. Synthetic approaches are reliant on the electrophilic activation of unactivated olefins, necessitating functionalization with nucleophiles. However, the reductive functionalization of unactivated and less activated olefins with electrophiles remains an ongoing challenge in synthetic chemistry. Here, we report the nucleophilic activation of inert styrenes through a photoinduced direct single electron reduction to the corresponding nucleophilic radical anion. Central to this approach is the multiphoton tandem photoredox cycle of the iridium photocatalyst [Ir(ppy)(2)(dtb-bpy)]PF6, which triggers in situ formation of a high-energy photoreductant that selectively reduces styrene olefinic it bonds to radical anions without stoichiometric reductants or dissolving metals. This mild strategy enables the chemoselective reduction and hydrofunctionalization of styrenes to furnish valuable alkane and tertiary alcohol derivatives. Mechanistic studies support the formation of a styrene olefinic radical anion intermediate and a Birch-type reduction involving two sequential single electron transfers. Overall, this complementary mode of olefin activation achieves the hydrofunctionalization of less activated alkenes with electrophiles, adding value to abundant olefins as valuable building blocks in modern synthetic protocols.

A new coumarin based fluorescent switch (HCBP) has been fabricated which displays high selective sensing towards Al3+ among other metal cations at physiological pH. On gradual addition of Al3+ specifically, HCBP shows a brilliant turn-on emission enhancement of about similar to 13-fold with about 50 nm red shift at 481 nm in MeOH/H2O (1/1, v/v) solution. The fluorescent switch is proven to be a reversible probe by addition of EDTA gradually into the HCBP-Al3+ solution. Detection limit as well as Binding constant values have been calculated and found to be in the order of 10(-9) M and 10(3) M-1 respectively. DFT and TDDFT studies are conducted with the probe to establish a similarity between theoretical and experimental outcomes. We can also use this new fluorescent switch as a biomarker kit as it has shown a brilliant potential in the application of live cell imaging using gastric cancer cell (AGS cell).

Volatiles of four zaoyu (Chinese traditional fermented fish) products prepared from different species of marine fish were analyzed by headspace solid-phase micro-extraction (HS-SPME) and comprehensive two-dimensional gas chromatography in combination with time-of-flight mass spectrometry (GC x GC/TOFMS). First, a 50/30 mu m DVB/CAR/PDMS was used and the influence of several parameters on the efficiency of HS-SPME such as extraction temperature, time, salting-out effect, and stirring were optimized, odor activity values (OAVs) of volatile compounds were computed based on the threshold values of aroma constituents; the characteristic volatiles and their odor characteristics of the four zaoyu were investigated. The results demonstrated that the most effective extraction of the analytes was obtained with a 40 min extraction at 50 degrees C with the addition of 20% NaCl and stirring at 300 r/min. Under these conditions, a total of 288 volatile components were tentatively identified based on mass spectra and comparison of linear retention indices in the four zaoyu products. Authenticated compounds included aldehydes, esters, alcohols, ketones, furans, lactones, nitrogen compounds, sulfur compounds, terpenes, phenols, etc. Among the identified types of volatile compounds, the number of esters is the largest, whereas the content of aldehydes is the highest. The results of OAVs comparisons proved that both aldehydes and esters provided the most significant contribution to the aromas of zaoyu, and each zaoyu product had its own unique active flavor components. Moreover, the OAVs of active flavor compounds common to the four examined zaoyu varied significantly. Our results substantiated that GC x GC/TOFMS could provide a robust technical means to understand the flavor characteristics of zaoyu and allow us to better evaluate and improve the flavor quality of the products with complex food matrix like zaoyu. Practical applications The method present in this research is suitable to characterize the volatile constituents of aquatic products, and could also be used for component characterization of similar complex samples such as fermented fish and foods. Understanding the key aroma compounds of fermented fish and its formation mechanism could provide a guide of process optimization and flavor regulation, contributing to further studies related to volatile compounds in the field of food flavor analysis.

Semicarbazones can exist in two tautomeric forms. In the solid state, they are found in the keto form. This work presents the synthesis, structures and spectroscopic characterization (IR and NMR spectroscopy) of four such compounds, namely the neutral molecule 4-phenyl-1-[phenyl(pyridin-2-yl)methylidene] semicarbazide, C19H16N4O, (I), abbreviated as HBzPyS, and three different hydrated salts, namely the chloride dihydrate, C19H17N4O+center dot Cl-center dot 2H(2)O, (II), the nitrate dihydrate, C19H17N4O+center dot NO3-center dot 2H(2)O, (III), and the thiocyanate 2.5-hydrate, C19H17N4O+center dot SCN-center dot 2.5H(2)O, (IV), of 2-[phenyl({[(phenylcarbamoyl) amino]imino})methyl]pyridinium, abbreviated as [H(2)BzPyS](+)center dot X-center dot nH(2)O, with X = Cl- and n = 2 for (II), X= NO3- and n = 2 for (III), and X = SCN- and n = 2.5 for (IV), showing the influence of the anionic form in the intermolecular interactions. Water molecules and counter-ions (chloride or nitrate) are involved in the formation of a two-dimensional arrangement by the establishment of hydrogen bonds with the N-H groups of the cation, stabilizing the E isomers in the solid state. The neutral HBzPyS molecule crystallized as the E isomer due to the existence of weak pi-pi interactions between pairs of molecules. The calculated IR spectrum of the hydrated [H(2)BzPyS](+) cation is in good agreement with the experimental results.

A novel fluorescent probe, TCF-IPY, has been designed and developed for highly selective and ratiometric detection of GSH based on the extend of the pi-conjugation system of imidazo[1,5-alpha]pyridine IPY-CHO. Upon addition of GSH, TCF-IPY displayed remarkable fluorescence variations (approximate 949-fold ratio changes) from 603 nm to 475 nm, thereby enabling GSH detection in a fine ratiometric manner. Moreover, TCF-IPY exhibited excellent selectivity toward GSH over other biologically related species including Cys and Hcy. The huge blue shifts both in absorption (259 nm) and emission spectra (128 nm), low cytotoxicity, high sensitivity (97 nM) and rapid response (240 s) of TCF-IPY make it a robust molecular tool for endogenous GSH investigation. Furthermore, TCF-IPY was also successfully used for ratiometric imaging of endogenous GSH in living MCF-7 cells and zebrafish.

A new methodology for the highly efficient and atom-economic oxidation of alcohols and benzylic compounds to the corresponding aldehydes and ketones with environmental-friendly hydrogen peroxide using a magnetic MOF nanocatalyst has been developed. We demonstrated that the resulting magnetic nanocomposite CoFe2O4@SiO2@MIL-53(Fe) can show excellent catalytic performances in the highly selective oxidation at room temperature, based on a synergetic effect between iron sites and CoFe2O4@SiO2. The nanocatalyst offers simple operation for recovery and the recycling test showed that it could be reused for successive runs without significant degradation in catalytic activity.
