Chemical compound
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 deadly.[1] This chemical can cross the blood–brain barrier, causing permanent brain damage. It is, however, considerably less toxic than dimethylmercury.
The resulting (CH3CH2)2Hg is a dense liquid (2.466 g/cm3) that boils at 58 °C at 16 torr. This extremely toxic compound is slightly soluble in ethanol and soluble in ether.
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]
