Sandmeyer Reaction Mechanism - Reactions, Examples, Uses, FAQs

Interestingly, the nucleophile can be a halide anion, , water, etc. To elucidate further, the Sandmeyer reaction mechanism commences with a transfer of a single electron from the to the diazonium. This results in the formation of a non-participating diazo radical as well as II halide.

Crystal Structures of Two New Complexes Produced by ...

An attempt to synthesize a complex between I and thioacetamide ta by a direct combination in aqueous solution, surprisingly, produced instead Cu4S2O32ta10·ta 1, a complex lacking but including thiosulfate. We know of no precedent for the production of thiosulfate from an aqueous solution of ta. Using a new synthetic approach, a complex of CuCN and ta was ...

Sandmeyer reaction -

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using salts as reagents or catalysts. It is an example of a radical-nucleophilic aromatic substitution. The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene, such as halogenation, cyanation, trifluoromethylation, and hydroxylation. …
