Diphenylzinc
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)ZnPh molecules in solid state.
Diphenylzinc is commercially available. It may be prepared by reaction of phenyllithium with zinc bromide:
2 PhLi + ZnBr → PhZn + 2 LiBrIt may also be prepared by the reaction of diphenylmercury with zinc metal.
