It is a well-known reaction mainly used for the conversion of an aryl amine to an aryl halide in the presence of Cu(I) halide via formation of diazonium salt intermediate. See full list on chemistry-reaction. This reaction is significant because it provides a straightforward method for synthesizing aryl halides, which are important intermediates in organic synthesis and materials science. Ber. AI generated definition based on: Experimental Organic Chemistry, 2016 Those substitution reactions that are catalyzed by cuprous salts are known as Sandmeyer reactions. The Sandmeyer reaction is a chemical reaction that synthesizes aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. General References ・Sandmeyer, T. The reaction is actually a two-step process, where the synthesis of aryl halides from primary aryl amines involves the formation of diazonium salts and the transformation of diazo intermediates into aryl halides (displacement with a nucleophile). 1884, . Fluoride substitution occurs on treatment with BF 4(–), a reaction known as the Schiemann reaction. Intro The “Sandmeyer Reaction” is a versatile method for replacing the amine group of a primary aromatic amine with a number of different substitutents. The diazonium can then undergo substitution reaction with various reactants, particularly copper(I) substrates. Traugott Sandmeyer discovered it in Aug 20, 2021 · Metal-catalyzed reactions play a vital part to construct a variety of pharmaceutically important scaffolds from past few decades. Learn about the Sandmeyer reaction, a radical-nucleophilic aromatic substitution reaction that replaces an amino group with different substituents.

Diazonium compounds are readily prepared from precursors such as nitro and aniline compounds. To carry out these reactions under mild conditions with low-cost easily available precursors, various new methodologies have been reported day by day. com 4 days ago · Nitroamines power a less explosive Sandmeyer reaction alternative Metal-free challenger to the classic deamination can be used in tandem with cross-coupling by Brianna Barbu October 30, 2025 3 min Jul 23, 2025 · In this article, we will see the basics of Sandmeyer's reaction, the mechanism of Sandmeyer's Reaction, its applications, its limitations, and the difference between Sandmeyer's and Gatterman's Reaction. The amine is treated with “nitrous acid” (HNO2) under acidic conditions, which produces the diazonium ion. Sandmeyer reaction is one of these, first discovered by Sandmeyer in 1884. When benzene diazonium salt is heated with cuprous chloride or cuprous bromide in presence of corresponding The Sandmeyer reaction is defined as a synthetic method that involves the replacement of an amino group on an aromatic ring with various substituents by converting the amino group into a diazonium salt, which can then be transformed into multiple functional groups. The Sandmeyer Reaction is a chemical reaction that involves the conversion of aryl diazonium salts into aryl halides using copper(I) halides. In this article, we will explore the principles, practical considerations, applications, and future directions of the Sandmeyer reaction is one of these, first discovered by Sandmeyer in 1884.
