Chemical compound

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]

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]
