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.

Hofmann, Natalie; Homberg, Leonard; Hultzsch, Kai C. published the artcile< Synthesis of tetrahydroquinolines via borrowing hydrogen methodology using a manganese PN3 pincer catalyst>, Reference of 5344-90-1, the main research area is tetrahydroquinoline preparation.

A straightforward and selective synthesis of 1,2,3,4-tetrahydroquinolines starting from 2-aminobenzyl alcs. and simple secondary alcs. is reported. This one-pot cascade reaction is based on the borrowing hydrogen methodol. promoted by a manganese (I) PN3 pincer complex. The reaction selectively leads to 1,2,3,4-tetrahydroquinolines thanks to a targeted choice of base. This strategy provides an atom-efficient pathway with water as the only byproduct. In addition, no further reducing agents are required.
