The sandmeyer reaction
WebbThe Sandmeyer reaction, involving the relevant amino precursors, is selective but laborious and often results in low yields. However, selective metallation, followed by displacement by halide, offers an alternative approach. Webb2 apr. 2024 · We should know that the Sandmeyer reaction is a type of organic substitution reaction in which we can synthesize aryl halides from aryl diazonium salts while Gattermann reaction is an organic substitution reaction in which we can formulate aromatic compounds.
