Diphenylzinc
Diphenylzinc (CAS: 1078-58-6) is an organozinc compound with the linear formula (C₆H₅)₂Zn and a molecular weight of 219.60 g/mol. It is a pyrophoric solid, meaning it can ignite spontaneously in air, and is primarily employed as a reagent in organic synthesis. Its applications extend to materials science and micro/nanoelectronics, particularly as a precursor for vapor deposition techniques.
Chemical Synthesis
Diphenylzinc serves as a valuable organometallic reagent in various organic transformations. It is particularly useful for the formation of carbon-carbon bonds through cross-coupling reactions and for the introduction of phenyl groups into organic molecules.
Materials Science and Micro/Nanoelectronics
As a precursor for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD), diphenylzinc is utilised in the fabrication of thin films. These films can possess unique electronic or optical properties relevant to microelectronic device manufacturing and advanced materials research.
Organozinc Reagent
Diphenylzinc is a key member of the Rieke and organozinc reagent family. It is employed in reactions requiring a source of phenylzinc species, offering controlled reactivity for specific synthetic targets.
