Diethylmercury is a flammable, colorless liquid, and one of the strongest known neurotoxins. This organomercury compound is described as having a slightly sweet smell, though inhaling enough fumes to notice this would be hazardous.[1] This chemical can cross the blood–brain barrier, causing permanent brain damage. It is, however, considerably less toxic than dimethylmercury.

Synthesis

[edit]

Diethylmercury can be obtained from the reaction between ethylmagnesium bromide and mercury(II) chloride.[2]

2 C2H5MgBr + HgCl2 → Hg(C2H5)2 + MgBr2 + MgCl2

Other methods are also known.[3]
