Tetrabutylammonium Bromide-Catalyzed Transfer Hydrogenation of Quinoxaline with HBpin as a Hydrogen Source

A metal-free environmentally benign, simple, and efficient transfer hydrogenation process of quinoxaline has been developed using the HBpin reagent as a hydrogen source. This reaction is compatible with a variety of quinoxalines offering the desired tetrahydroquinoxalines in moderate-to-excellent yields with Bu4NBr as a noncorrosive and low-cost catalyst.

Method for synthesizing quinoxaline compound under visible light induced iron catalysis condition

The invention belongs to the technical field of compound synthesis, and particularly relates to a method for synthesizing quinoxaline compounds under visible light induced iron catalysis conditions. The method comprises the following steps: by taking non-activated aliphatic amine and o-phenylenediamine as raw materials, under the action of a photosensitizer, under the illumination of visible light, reacting in a solvent at room temperature and under oxygen conditions to generate the quinoxaline compound. The method has better substrate universality and relatively mild reaction conditions, not only realizes synthesis of the quinoxaline compound for the first time, but also widens the field of organic synthesis.

Elemental fluorine. Part 10.1 Selective fluorination of pyridine, quinoline and quinoxaline derivatives with fluorine-iodine mixtures

Selective fluorination of a range of pyridine and quinoline substrates to give corresponding 2-fluoro-derivatives can be readily achieved in high yield at room temperature using elemental fluorine-iodine mixtures. Reaction of fluorine with iodine forms, in situ, systems that function like sources of both iodonium and fluoride ions and fluorination of heterocyclic derivatives is suggested to proceed by fluoride ion attack on intermediate W-iodo-heterocyclic species. Quinoxaline derivatives react under similar conditions to give either the 2-fluoro- or 2,3-difluoro-quinoxaline derivatives depending on the ratio of fluorine passed through the solution. In related processes, pyridine can be alkoxylated upon reaction of an appropriate alcohol and fluorine.
