WebThe preparation of alkyl iodide from alkyl bromide or chloride with potassium or sodium iodide in acetone is generally known as the Finkelstein reaction. This reaction is a simple nucleophilic substitution (often via S N 2) and iodide is found to be stronger nucleophile than bromide or chloride. WebApr 5, 2024 · The Finkelstein reaction is another one of the important name reactions of organic chemistry. It is used in the preparation of haloalkanes or alkyl halides. It is a substitution nucleophilic bimolecular (SN2 reaction) halogen exchange reaction. It is named after German Chemist Hans Finkelstein.
The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. 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.

WebThe standard Finkelstein reaction involves treating an alkyl chloride or alkyl bromide with a solution of sodium iodide in acetone to convert it to an alkyl iodide. Unlike sodium chloride and sodium bromide, sodium iodide dissolves in acetone. http://www.adichemistry.com/organic/namedreactions/finkelstein/finkelstein-reaction-1.html
