WebDec 9, 2024 · It is called Finkelstein reaction. In this reaction, I – ion being a stronger nucleophile displaces Br – ion. NaBr formed is insoluble in dry acetone whereas Nal dissolves. This shifts the equilibrium in the forward direction. Under the reaction conditions allylic halogenation will take place. WebTherefore, usually Cu-and Ni-mediated Finkelstein-type reactions are performed under harsh conditions (> 100°C) even for comparatively simple substrates, [48, 49] potentially limiting their ...

Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not. The reaction is driven toward products by mass … See more The Finkelstein reaction named after the German chemist Hans Finkelstein, is an SN2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an See more The aromatic chlorides and bromides are not easily substituted by iodide, though they may occur when appropriately catalyzed. The so-called "aromatic Finkelstein reaction" is catalyzed by copper(I) iodide in combination with diamine ligands. See more Alkyl halides differ greatly in the ease with which they undergo the Finkelstein reaction. The reaction works well for primary (except for neopentyl) halides, and exceptionally well for allyl, benzyl, and α-carbonyl halides. Secondary halides are far less reactive.
