Zinc-copper couple (CAS 53801-63-1)

The zinc-copper couple is used as a reagent in organic synthesis to facilitate the reduction of various functional groups, such as alkenes, alkynes, and carbonyl compounds. When added to a reaction mixture, the zinc-copper couple acts as a source of single electrons, which initiates a chain reaction leading to the reduction of the targeted functional group. This process involves the transfer of electrons from the zinc-copper couple to the substrate, resulting in the formation of a radical intermediate. The radical intermediate then undergoes further reactions to yield the reduced product. The zinc-copper couple′s ability to generate radicals may be a function in the synthesis of complex organic molecules, allowing for the selective reduction of specific functional groups under mild reaction conditions. Its mechanism of action involves the formation of radical intermediates, which can then participate in various chemical transformations, enabling the efficient synthesis of diverse organic compounds.
