Copper(I) acetate (cuprous acetate) is an organic copper salt of acetic acid with chemical formula CH₃COOCu.

Under standard conditions, copper(I) acetate is a colorless, odorless crystal.

Chemical properties

When interacting with water (hydrolysis), copper(I) hydroxide (CuOH) is formed:

CuCH₃COO + H₂O → CuOH + CH₃COOH

In air, it oxidizes to copper(II) acetate. It forms adducts with organic substances.

Synthesis

• Reaction of copper(II) acetate with hydrogen or copper (reduction process):

2 (CH₃COO)₂Cu + H₂ → 2 CH₃COOCu + 2 CH₃COOH

(CH₃COO)₂Cu + Cu → 2 CH₃COOCu

• Interaction of hydroxylammonium sulfate and copper(II) acetate in the presence of ammonium acetate.
• Sublimation of copper(II) acetate in vacuum.

Application

Copper(I) acetate is used as a catalyst for the oxidation of phenols.
