Diphenylzinc is an organozinc compound. It is commonly used as the synthetic equivalent of a Ph⁻ synthon. Solvent-free diphenylzinc exists as dimeric PhZn(μ-Ph)₂ZnPh molecules in the solid state.^[1]

The dimeric solid state form of diphenylzinc.

Diphenylzinc is commercially available. It may be prepared by reaction of phenyllithium with zinc bromide:^[2]

2 PhLi + ZnBr₂ → Ph₂Zn + 2 LiBr

It may also be prepared by the reaction of phenylmagnesium bromide with zinc chloride or diphenylmercury with zinc metal.^[3][4]
