Benzil is a standard building block in organic synthesis. It condenses with amines to give diketimine ligands. A classic organic reaction of benzil is the benzilic acid rearrangement, in which base catalyses the conversion of benzil to benzilic acid. This reactivity is exploited in the preparation of the drug phenytoin. See more 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 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. … 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 … 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 decomposition with formation of free-radical species and formation of cross-links within the material. … See more WebDescription. Benzil is used as a pharmaceutical intermediate and uv curing resin photosensitizer. In polymer chemistry, it is used as a photoinitiator. Further, it serves as a potent inhibitor of human carboxylesterases. It is used in the preparation of diketimines by reacting with amines.
WebStep-by-step solution. 100% (3 ratings) for this solution. Step 1 of 3. In the mechanism of sodium borohydride reduction, the first step is the reduction of one of the ketones found in benzil. This occurs through a concerted step, in which new B-O and C-H bonds form while one of the B-H bonds and the C=O double bond are broken.
