WebJul 20, 2016 · Finkelstein reaction is a halogen exchange reaction between haloalkane and a salt of a different halogenide. R − C H X 2 − C l + K I R − C H X 2 − I + K C l. The driving force in this reaction is precipitation of K C l. It is important to find a solvent that would dissolve K I better than K C l. WebThe Finkelstein reaction of 89 (i.e., NaI in acetone) afforded spirocyclization precursor 90. Attempted spirocyclization using Heathcock’s original conditions (i.e., only AgOTf; no base) lead to substantial decomposition of substrate.

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 ... WebThe Finkelstein reaction is an organic reaction where an alkyl halide is converted into another alkyl halide by reacting with a metal halide salt. This is an equilibrium process and it is driven forward by taking advantage of the poor solubility in acetone of the newly formed metal halide salt (Le Chatelier's principle). WebFINKELSTEIN REACTION * The Finkelstein reaction involves the exchange of one halogen for another, especially, in primary alkyl halides. It is used to synthesize one alkyl halide from another. In the classical version of Finkelstein reaction, a primary alkyl halide, RX is treated with an alkali metal halide, like NaX' or KX', in excess in acetone. small business internet att
