Benzil (i.e. Bz2, systematically known as 1,2-diphenylethane-1,2-dione) is the organic compound with the formula (C6H5CO)2, generally abbreviated (PhCO)2. This yellow solid is one of the most common diketones. Its main use is as a photoinitiator in polymer chemistry. See more The compound's most noteworthy structural feature is the long carbon-carbon bond of 1.54 Å, which indicates the absence of pi-bonding between the two carbonyl centers. The PhCO centers are planar, but the pair … See more Most benzil can be used as a photoinitiator in the free-radical curing of polymer networks. It absorbs ultraviolet radiation at a wavelength of 260 nm, leading to … See more Benzil is prepared from benzoin, for example with copper(II) acetate: PhC(O)CH(OH)Ph + 2 Cu → PhC(O)C(O)Ph + 2 H + 2 Cu Other suitable oxidizing agents such as nitric acid (HNO3) are used routinely.
