In 2022,Abednatanzi, Sara; Gohari Derakhshandeh, Parviz; Dalapati, Sasanka; Veerapandian, Savita K. P.; Froissart, Anne-Claire; Epping, Jan Dirk; Morent, Rino; De Geyter, Nathalie; Van Der Voort, Pascal published an article in ACS Applied Materials & Interfaces. The title of the article was 《Metal-Free Chemoselective Reduction of Nitroarenes Catalyzed by Covalent Triazine Frameworks: The Role of Embedded Heteroatoms》.Formula: C5H5BrN2 The author mentioned the following in the article:
Development of robust nanoporous covalent triazine frameworks (CTFs) as metal-free catalysts for the green chemoselective reduction of nitroarenes. The turnover frequency was found to be 43.03 h-1, exceeding activities of the heteroatom-doped carbon nanomaterials by a factor of 30. The XPS and control experiments provided further insights into the nature of active species for prompt catalysis. This report confirmed the importance of quaternary ‘N’ and ‘F’ atom functionalities to create active hydrogen species via charge delocalization as a critical step in improving the catalytic activity. In the part of experimental materials, we found many familiar compounds, such as 6-Bromopyridin-3-amine(cas: 13534-97-9Formula: C5H5BrN2)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Formula: C5H5BrN2
