Benzophenone is a naturally occurring organic compound with the formula (C 6 H 5) 2 CO, generally abbreviated Ph 2 CO. Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest ...
One broad classification subdivides ketones into symmetrical and unsymmetrical derivatives, depending on the equivalency of the two organic substituents attached to the carbonyl center. Acetone and benzophenone ((C 6 H 5) 2 CO) are symmetrical ketones. Acetophenone (C 6 H 5 C(O)CH 3) is an unsymmetrical ketone.
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
Benzophenone may undergo the pinacol coupling photochemically. [4] Benzaldehyde may also be used as a substrate with the use of catalytic vanadium(III) chloride and aluminium metal as the stoichiometric reductant. [5] This heterogeneous reaction in water at room temperature yields 72% after 3 days with 56:44 dl:meso composition.
Many ketones contain the benzoyl group. They have the formula C 6 H 5 CO–R, an important example being benzophenone. Benzoyl esters and amides are common in organic chemistry. The esters are used as a protecting groups in organic synthesis, [4] which can be easily removed by hydrolysis in dilute basic solution.
