Synthetic Route of C5H5BrN2On March 4, 2020, Biot, Nicolas; Bonifazi, Davide published an article in Chemistry – A European Journal. The article was 《Concurring Chalcogen- and Halogen-Bonding Interactions in Supramolecular Polymers for Crystal Engineering Applications》. The article mentions the following:
The engineering of crystalline mol. solids through the simultaneous combination of distinctive non-covalent interactions is an important field of research, as it could allow chemist to prepare materials depicting multi-responsive properties. It is in this context that, pushed by a will to expand the chem. space of chalcogen-bonding interactions, a concept is put forward for which chalcogen- and halogen-bonding interactions can be used simultaneously to engineer multicomponent co-crystals. Through the rational design of crystallizable mols., chalcogenazolo pyridine scaffold (CGP) modules were prepared that, bearing either a halogen-bond acceptor or donor at the 2-position, can interact with suitable complementary mol. modules undergoing formation of supramol. polymers at the solid state. The recognition reliability of the CGP moiety to form chalcogen-bonded dimers allows the formation of heteromol. supramol. polymers through halogen-bonding interactions, as confirmed by single-crystal X-ray diffraction anal. The results came from multiple reactions, including the reaction of 2-Bromopyridin-3-amine(cas: 39856-58-1Synthetic Route of C5H5BrN2)
2-Bromopyridin-3-amine(cas: 39856-58-1) belongs to anime. Milder oxidation, using reagents such as NaOCl, can remove four hydrogen atoms from primary amines of the type RCH2NH2 to form nitriles (R―C≡N), and oxidation with reagents such as MnO2 can remove two hydrogen atoms from secondary amines (R2CH―NHR′) to form imines (R2C=NR′). Tertiary amines can be oxidized to enamines (R2C=CHNR2) by a variety of reagents.Synthetic Route of C5H5BrN2
