Cadet's fuming liquid

Cadet's fuming liquid was a red-brown oily liquid prepared in 1760 by the French chemist Louis Claude Cadet de Gassicourt (1731-1799) by the reaction of potassium acetate with arsenic trioxide.[1] It consisted mostly of dicacodyl (((CH3)2As)2) and cacodyl oxide (((CH3)2As)2O).

Space-filling model of dicacodyl
Ball-and-stick model of cacodyl oxide

The global reaction (mass balance) corresponding to the oxide formation is the following:

4 CH3COOK + As2O3 → ((CH3)2As)2O + 2 K2CO3 + 2 CO2

These were the first organometallic substances prepared; as such, Cadet has been regarded as the father of organometallic chemistry.[2]

This liquid develops white fumes when exposed to air, resulting in a pale flame producing carbon dioxide, water, and arsenic trioxide. It has a nauseating and very disagreeable garlic-like odor.

Around 1840, Robert Bunsen did much work on characterizing the compounds in the liquid and its derivatives. His research was important in the development of radical theory.
