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 ...
