Copper(I) acetate is an inorganic salt with the formula CuC2H3O2. It can be used as a catalyst in the oxidation of phenols, and as a reactant in the production of vinyl acetates.
Copper(I) acetate can be made from copper(II) acetate by heating it to 220 °C in a oxygen free, anhydrous atmosphere with metallic copper.
Copper(I) acetate can also be synthesized using copper(I) oxide and glacial acetic acid.
Copper(I) acetate reacts readily with water to create copper(I) oxide.
