Ph2Zn
Ph2Zn, also known as Diphenylzinc, is an organozinc compound with the chemical formula (C6H5)2Zn. It is a white crystalline solid that is soluble in organic solvents but insoluble in water. Diphenylzinc is commonly used in organic synthesis as a reagent for the formation of carbon-carbon bonds. It is particularly useful in the Suzuki-Miyaura cross-coupling reaction, where it reacts with organohalides to form biaryl compounds. The compound is typically prepared by the reaction of zinc metal with diphenylmercury or by the transmetalation of diphenylmagnesium bromide with zinc chloride. Diphenylzinc is highly reactive and should be handled with care to avoid decomposition and the release of toxic zinc fumes. It is also pyrophoric, meaning it can ignite spontaneously in air, further emphasizing the need for careful handling. Despite its reactivity, diphenylzinc is a valuable tool in the synthesis of complex organic molecules, particularly in the pharmaceutical and materials science industries.
