The success of this reaction depends on the below conditions. For Example: Synthesis of chrysochlamic acid. September 2006; Journal of chemical education 83(9) DOI: … products, since KCl and KBr are insoluble in acetone and are consequently Since $\ce{KCl}$ keeps precipitating the reaction will be driven to the desired product. Secondary halides are far less reactive. The chlorine atom in aryl chlorides (with electron-withdrawing substituents) can be replaced by fluorine using a solution of potassium fluoride in polar solvents such as DMF and DMSO and high temperatures. the metal salt in the solvent used.

The so-called "aromatic Finkelstein reaction" is catalyzed by copper(I) iodide in combination with diamine ligands. This reaction takes place at an equilibrium process by taking the advantage of poor acetone solubility in metal halide salt that is newly formed. The reaction works good with the primary halides but better with α-carbonyl halides and allyl benzyl. Below some relative rates of reaction (NaI in acetone at 60°):[4][5], In modern usage the definition of the reaction has been expanded to include the conversion of alcohols to alkyl halides by first converting the alcohol to a sulfonate ester (tosylates or mesylates are usually used), and then performing the substitution. This page has been viewed approximately 11073 times since records began. This reaction is important because there are many ways to make $\ce{RCH2Cl}$, but making $\ce{R-CH2-I}$ is difficult. hexanes to Et2O solution  (2 X 200mL) and the grey fine precipitate was removed by filtration through a medium porosity fritted funnel.2  The slightly clouded3 yellow-tinged filtrate was washed with ≈100 mL of a 10% w./w. better stabilized than the other in a given solvent (see Nucleophilic Substitution). As the sodium iodide is soluble in the acetone, but the sodium bromide and sodium chloride are not soluble in the acetone. the anion, whether a good leaving group is present, and whether one anion is SN2 Reaction. S. S. Shinde, B. S. Lee, D. Y. Chi, Org. Ges., 1910, 43, 1528. Dtsch. KF, KI) leads to replacement of the halogen via an [10] Nickel bromide and tri-n-butylphosphine have been found to be suitable catalysts as well.[11]. The classic Finkelstein reaction involves the process of an alkyl bromide or an alkyl chloride into an alkyl iodide which is treated with a sodium iodide solution in acetone. The mechanism of the Finkelstein reaction is single-step \(S_{N}2\) reaction with stereochemistry inversion. Sodium iodide (37.47 g, 0.250 mol) was then added all at once to the flask .

[5] Such reactions usually employ polar solvents such as dimethyl formamide, ethylene glycol, and dimethyl sulfoxide. Hans Finkelstein (17 May 1885, Leipzig, Germany - December 1938) was a German chemist.He is particularly known for the Finkelstein reaction developed by and named after him.. Biography. As the sodium iodide is soluble in the acetone, but the sodium bromide and sodium chloride are not soluble in the acetone. The Finkelstein reaction is an organic reaction where an alkyl halide is converted into another alkyl halide by reacting with a metal halide salt.
