Chemical compound
Cacodyl oxide is a chemical compound of the formula [(CH3 )2 As]2 O. This organoarsenic compound is primarily of historical significance since it is sometimes considered to be the first organometallic compound synthesized in relatively pure form.[ 1] [ 2]
"Cadet's fuming liquid ", which is composed of cacodyl and cacodyl oxide, was originally synthesized by heating potassium acetate with arsenic trioxide . It has a disagreeable odor and is toxic.
The molecular structure of [Ph2 As]2 O (Ph = phenyl ), the tetraphenyl analogue of cacodyl oxide, has been established by X-ray crystallography .[ 3]
