Chemical Properties

White to light yellow crystalline powder

Uses

Diphenylzinc is used as the synthetic equivalent of ph- synthon. It is also useful in a Michael 1,4-addition reactions. It is used as a catalyst for propylene oxide polymerization in benzene medium. Further, it is a reactive coupling compound in Negishi cross-coupling reactions. In addition to this, it utilized in the preparation of arylcopper, arylsilver and arylgold compounds.
