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 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). WebThe 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. list of horticultural plants
