The preparation of nano CuNiFeO and its application in the synthesis of quinolines was reported. The prepared nanocatalyst was characterized using various characterization techniques such as XRD, FEG-SEM, EDX, HR-TEM and XPS. Nano CuNiFeO as a heterogeneous catalyst showed a very high efficiency towards double dehydrogenation tandem cyclization reaction of 2-amionbenzyl alc. with alcs. resulting into a simple, sustainable and environment friendly synthesis of quinolines. Due to the magnetic property associated with nanocatalyst, it was easily separated from the reaction mixture using external magnet and could be reused up to five cycles. To the best of our knowledge, this is for the first time a heterogenous magnetic CuNiFeO nanocatalyst was being reported for this reaction.

Kulyk, Dmytro S.; Wan, Qiongqiong; Sahraeian, Taghi; Badu-Tawiah, Abraham K. published the artcile< Dehydration of gas-phase benzyl amine alcohols studied at atmospheric pressure>, Recommanded Product: (2-Aminophenyl)methanol, the main research area is benzyl alc dehydration mechanism mass spectrum.

Gas-phase ion chem. is a useful approach for the investigation of phys. organic chem. and the study of reactivity, structure, and thermochem. properties of ionic and neutral organic substrates. Herein, one-step dehydration of gas-phase benzyl amine alcs. to give benzazetidines was discovered without the use of catalysts. Mechanistic investigations of the gas-phase dehydration reactions were explored to study the possible influence of charged microdroplet acceleration during electrospray ionization (ESI) and collisions occurring during ion transfer through the atm. pressure interface (API) of the mass spectrometer. The product ion distribution was observed to be less sensitive to droplet effects (spray distance and voltage), and temperature of transfer capillary in the API. However, the product ion distribution exhibit high sensitivity to different S-lens radio frequency (RF) voltage of the API, providing evidence that the dehydration reaction is driven by collisions during ion transfer in the API. With this insight, we developed atm. pressure thermal dissociation platform that allowed thermal-induced collisions outside of the mass spectrometer when the benzyl amine alcs. are carried through a heated coiled tube. Up to 98% dissociation efficiency was achieved with the coiled tube heated to a temperature of 200°C, yielding only the desired benzazetidine product. By performing the atm. pressure thermal dissociation experiment outside of the mass spectrometer, we believe it will be straightforward to collect the dehydration product.

Chang, Jun Jie; Pan, Houwen Matthew; Goto, Atsushi published the artcile< Synthesis of vinyl iodide chain-end polymers via organocatalyzed chain-end transformation>, Formula: C9H8O, the main research area is vinyl iodide chain end polymer organocatalyzed transformation.

In the presence of alkynes (CH=C-R2), iodide chain-end polymers (Polymer-I) were successfully transformed to vinyl iodide chain-end polymers (polymer-CH=CR2-I) in a single step via organocatalysis. This reaction is completely metal-free and easy to carry out without using special reagents or special conditions. The polymers encompassing polyacrylates and polymethacrylate, and addnl. functionalities (e.g., OH and CF3) were also incorporated into the R2 moiety. The obtained Polymer-CH=CR2-I further served as a useful precursor for copper-catalyzed cross-coupling reactions with various thiols (R3-SH) to yield vinyl sulfide chain-end polymers (polymer-CH=CR2-SR3) with various R3 moieties. Interestingly, under selected conditions, this organocatalysis also offered block-like copolymers containing a conjugated oligo-alkyne segment and a non-conjugated polyacrylate segment. Exploiting the unique structure, the block-like copolymer was used as an efficient dispersant of carbon nanotubes.

Yang, Bo; Li, Shi-Jun; Wang, Yongdong; Lan, Yu; Zhu, Shifa published the artcile< Hydrogen radical-shuttle (HRS)-enabled photoredox synthesis of indanones via decarboxylative annulation>, Recommanded Product: (4-Ethynylphenyl)methanol, the main research area is phenylglyoxalic acid acetylene iridium photocatalyst regioselective decarboxylative cyclization; dihydroindenone preparation.

In this work, a HRS-enabled decarboxylative annulation of carbonyl compounds via photoredox catalysis for the synthesis of indanones was developed. This protocol features broad substrate scope, excellent functional group tolerance, internal hydrogen radical transfer, atom- and step-economy. Critical to the success of this process is the introduction of water, acting as both HRS and hydrogen source, which was demonstrated by mechanistic experiments and d. functional theory (DFT) calculations Importantly, this mechanistically distinctive HAT provides a complement to that of typical proton-shuttle-promoted, representing a breakthrough in hydrogen radical transfer, especially in the inherently challenging 1,2- or 1,3-HAT.

Rahimi, Atyeh; Nojavan, Saeed published the artcile< Electromembrane extraction of verapamil and riluzole from urine and wastewater samples using a mixture of organic solvents as a supported liquid membrane: Study on electric current variations>, Name: 2-Ethylhexan-1-ol, the main research area is electromembrane extraction verapamil riluzole urine wastewater sample; organic solvent mixture supported liquid membrane elec current effect; electromembrane extraction; riluzole; urine; verapamil; wastewater.

The application of a mixture of organic solvents as a supported liquid membrane for improving the efficiency of the electromembrane extraction procedure was studied. The extraction process was followed by HPLC anal. of two model drugs (verapamil and riluzole). In this research, four organic solvents, including 1-heptanol, 1-octanol, 2-nitrophenyl octyl ether, and 2-Et hexanol, were selected as model solvents and different binary mixtures (volume/volume 2:1, 1:1 and 1:2) were used as the supported liquid membrane. The mixture of 2-Et hexanol and 1-otanol (volume/volume, 2:1) improved the extraction efficiency of model drugs by 1.5 to 12 times. Extraction efficiency is greatly influenced by the level of elec. current. For various mixtures of organic solvents, the elec. current fluctuated between 50 and 2500 μA, and the highest extraction efficiencies were obtained with low and stable elec. currents. Finally, the optimized extraction condition was validated and applied for the determination of model drugs in urine and wastewater samples.

Chaintreau, Alain; Keller, Urs; Zellner, Barbara; Nguy, Kelly; Leocata, Sabine; Begnaud, Frederic published the artcile< From the representativeness of sampled odors to an olfactive camera>, SDS of cas: 104-76-7, the main research area is odor static trap headspace olfactive camera; aroma; fragrance; odor; olfactive camera; quantitation; representativeness; static-and-trapped headspace.

Although representativeness is often a prerequisite when sampling odors, the methods used have never been assessed from the anal. and sensory perspective simultaneously. We validate several critical innovations in the methods used to sample odors, starting with a previously developed static-and-trapped headspace (S&T-HS) cell, to minimize sorptive biases and allow for thermodesorption of trapped odors. The addition of a desorption oven allows for restoration and testing of odors sampled by not only S&T-HS but also other techniques (solid-phase microextraction, headspace sorptive extraction, purge-and-trap headspace). The S&T-HS cell exhibits satisfactory representativeness, much higher than the three other techniques. This allows, for the first time, a proposal to use this technol. as an olfactive camera to capture and restore an odor. The method was tested on a sample of a complex fresh ashtray odor.

Armylisas, Abu Hassan N.; Fauzi, Siti H. M.; Mohd, Noor K.; Yeong, Shoot K.; Zainab, Idris; Azwadi, Che Sidik N. published the artcile< Excellent Properties of Dimer Fatty Acid Esters as Biolubricant Produced by Catalyst- and Solvent-Free Esterification>, Formula: C8H18O, the main research area is dimer fatty acid ester biolubricant catalyst solvent free esterification.

Currently most technologies available to produce esters require acid or base catalysts for esterification or transesterification reactions. Production of dimerate esters (DE) exhibiting potential as a biolubricant for low temperature applications using catalyst- and solvent-free approaches is presented in this article. Hydrogenated C36 dimer acid and alc. are reacted under the following conditions: dimer acid/alc. (1:4.5 molar ratio), 150-200 °C, 24 h, 3Å mol. sieve (15% weight/weight). The performances of four DE species-dibutyl, dihexyl, di-(2-ethylhexyl), and dioctyl dimerate-as lubricant base stocks are evaluated by kinematic viscosity, viscosity index, cloud and pour point (cold flow properties) as well as oxidative stability, and compared with com. synthetic lubricant base stock and DE, Radialube 7121. High viscosity indexes ranging between 129 and 138 are observed for the synthesized DEs, which are comparable with two com. base stock, polyalpha olefin (PAO), and polyolester (POE). Significantly low pour point, less than -42 °C, is observed for di-(2-ethylhexyl) dimerate attributed to the branching of the side chain. The DEs are categorized as ISO VG 68 based on their viscosity according to ISO 3448 classification and show potential as biolubricant with high viscosity index and excellent cold flow properties. Practical Applications: DFAE obtained have high potential to be used as lubricant base stock for equipment and machinery operating at extremely low temperature
