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.

## Synthesis

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.

${\displaystyle {\ce {Cu(C2H3O2)2 + Cu -> 2CuC2H3O2}}}$

Copper(I) acetate can also be synthesized using copper(I) oxide and glacial acetic acid.

${\displaystyle {\ce {Cu2O + 2HC2H3O2 -> 2CuC2H3O2 + H2O}}}$

## Reactions

Copper(I) acetate reacts readily with water to create copper(I) oxide.
