Rosenbach Reaction

Rosenbach Reaction is a chemical reaction between halogens and reducing intermediates, including many thiols, selenuriums, etc., resulting in the formation of an organohalide compound.

The Rosenbach reaction is a key step in nucleophilic substitution reactions, such as dehydrohalogenation under the influence of a nucleophile. The Rosen reaction is used in the synthesis of furan from derivatives of a multiple bond (for example, 2-oxoal).

In the case of reactions with halogenated hydrocarbons, reducing agents such as thiols and sulfides, radicals such as SO2CH2 radicals or an allylic radical can be active.
