The French chemist Louis Claude Cadet de Gassicourt (1731-1799) synthezised a red liquid by the reaction of potassium acetate with arsenic trioxide.

4KCH₃COO + As₂O₃ → As₂(CH₃)₄0 + 4K₂C0₃ + C0₂

The liquid contains a mixture of cacodyl and cacodyl oxide. These were the first metallorganic substances prepared.
