Diphenylzinc
# Diphenylzinc

Diphenylzinc is an organozinc compound. It is commonly used as the synthetic equivalent of a $Ph^−$ synthon. Solvent-free diphenylzinc exists as dimeric $PhZn(μ-Ph)_2ZnPh$ molecules in the solid state.

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

    2 PhLi + $ZnBr_2$ → $Ph_2Zn$ + 2 LiBr

It may also be prepared by the reaction of phenylmagnesium bromide with zinc chloride or diphenylmercury with zinc metal.
