In the course of present investigations, it was found that dichloroamine T could be an efficient reagent for the conversion of oximes into the corresponding carbonyl compounds Herein the synthesis of 1H-1,5-benzodiazepine derivatives I [R = pyrrol-2-yl, 2-pyridinyl, 2-thienyl, etc.] from heteroaromatic ketones and acetone equivalent was obtained using dichloroamine-T. On the other hand, when diamine (1,2-phenylene diamine or 1,2-naphthalene diamine) with heterocyclic ketone (acetyl pyridine or acetyl pyrazines) in the presence of concentrate HCl and SiO2 was refluxed, quinoxaline derivatives, II [R = 2-pyrazinyl, 2-pyridinyl, 2-thienyl, etc.] as yellow crystalline solids were isolated in high yields. In the part of experimental materials, we found many familiar compounds, such as 4-Acetylpyridine(cas: 1122-54-9Recommanded Product: 1122-54-9)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Recommanded Product: 1122-54-9
