A palladium-catalyzed synthesis method of fluorenones was developed. A variety of bis(2-bromophenyl)methanols underwent the reaction smoothly in the presence of Pd(OAc)2, affording a series of fluorenones in moderate to good yields (two steps). Mechanistic studies revealed that the reaction might be triggered by oxidation of alc. followed by intramol. reductive coupling. The experimental process involved the reaction of 2-Bromonicotinaldehyde(cas: 128071-75-0Recommanded Product: 128071-75-0)
2-Bromonicotinaldehyde(cas: 128071-75-0) 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: 128071-75-0
