WebJun 4, 2024 · 1 Answer Sorted by: 2 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 anhydrous s acetone ( Wikipedia ). You can find here why this reaction works in this manner. WebAbstract. The 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. Under normal conditions, this type of ...

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. WebNational Council of Educational Research and Training songs with aba form

WebJun 16, 2024 · Finkelstein reaction is used to make alkyl halides and haloalkanes. The nucleophilic bimolecular halogen transfer process can be replaced with it. The Finkelstein reaction is frequently mentioned as the halogen exchange reaction or the halex reaction. It is a S N 2 reaction (substitution nucleophilic bimolecular). WebTherefore, we have developed a quantitative kinetics laboratory exercise featuring the Finkelstein reaction (S N 2) for use in the first-semester organic chemistry course that utilizes nonaqueous conductivity as the method by which relevant structure–temperature–solvent effects are examined. 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.
