Application

Zinc powder is generally used as a reagent for the Clemmensen reduction of ketones.
It can also be used as a:
  • Reducing agent in the preparation of graphene from graphene oxide using ultrasonication method.
  • Reducing agent in the oxidation of benzene to phenol by vanadium substituted heteropolyacid catalyst and oxygen oxidant.
  • Reactant in the preparation of alkyl zinc reagents by direct insertion of zinc powder into unactivated alkyl bromides and chlorides.
  • Catalyst in selective Fries rearrangement of acetylated phenols.
