Finkelstein反应,以德国化学家Hans Finkelstein的名字命名。它是指伯卤代烷或伯醇磺酸酯与金属卤代物(如KF, KI)通过SN2 反应得到另一种卤代物的反应。.
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 acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not. The reaction is driven toward products by mass … See more The Finkelstein reaction named after the German chemist Hans Finkelstein, is an SN2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an See more The aromatic chlorides and bromides are not easily substituted by iodide, though they may occur when appropriately catalyzed. The so-called "aromatic Finkelstein reaction" is catalyzed by copper(I) iodide in combination with diamine ligands. See more Alkyl halides differ greatly in the ease with which they undergo the Finkelstein reaction. The reaction works well for primary (except for neopentyl) halides, and exceptionally well for allyl, benzyl, and α-carbonyl halides. Secondary halides are far less reactive. See more • Halex process, also a salt metathesis, but for conversion of aryl chlorides to aryl fluorides See more WebApr 7, 2024 · Bromine reacts with alkenes and alkynes through addition reactions and with aldehydes through oxidation (Figure 6.53). It gives no reaction with aromatics, making this a good test to distinguish alkenes from aromatics. Figure 6.53: Reaction of an alkene, alkyne, and aldehyde with bromine.
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.
