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 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 diphenylmercury with zinc metal.[3]
