Webequilibrium reaction in which the position of the equilibrium is influenced by the solubility difference of the halide salts, in analogy to the Finkelstein reaction (halogen exchange in alkyl halides). For example, NaI in dioxane or n-butanol provides higher equilibrium conversion (99.5%) of 5-bromo-m-xylene into 5-iodo-m-xylene than WebThe Finkelstein reaction is a Substitution Nucleophilic Bimolecular reaction (SN2 Reaction) that involves the exchange of halogen atoms. It is named after Hans Finkelstein, a German chemist. It is an organic reaction that uses an alkyl halide exchange into another alkyl halide through a reaction wherein the metal halide salt is used.

WebSep 15, 2016 · The aromatic Finkelstein iodination reaction is a powerful method of preparing valuable aryl iodides from cheap but less reactive aryl bromides and chlorides. This protocol describes a... 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.
WebFinkelstein Reaction is a simple and easy process that maintains equilibrium. The insolubility of the newly formed metal halide salt in acetone supports the forward reaction. The reaction is known as a single step bimolecular nucleophilic substitution reaction which is also known by the name of an SN2 reaction.
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.
