Zinc is a low cost reagent that is used in a wide variety of reduction reactions and in the making of organozinc reagents that allow the formation of new carbon-carbon bonds. Zinc sometimes requires activation before use.

Common Uses:

Reagent for reduction of nitro groups to amines

Reagent for the reduction of conjugated double bonds

Reagent for the preparation of organozinc (Negishi) reagents


Zinc is relatively non-toxic, although in large amounts it can be harmful.
