Diphenylmercury is the organomercury compound with the formula Hg(C6H5)2. It is a white solid.[2] The compound is of historic interest as a particularly stable organometallic compound but it finds few uses because of its high toxicity.
Preparation
[edit]Commercially available, this compound can be prepared by several routes. It results from treating phenylmercury acetate with sodium stannite,[3] by the reaction of mercuric halides with phenylmagnesium bromide,[4] and the reaction of bromobenzene with sodium amalgam.[5]
Safety
[edit]Diphenylmercury is highly toxic.
