Preparation

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

Diphenylmercury is highly toxic.
