Benzoyl group

From Wikipedia, the free encyclopedia
The benzoyl functional group.

In organic chemistry, benzoyl (/ˈbɛnzoʊɪl/, BENZ-oh-il)[1] is the functional group with the formula C6H5CO-.[2][3]

The term "benzoyl" should not be confused with benzyl, which has the formula C6H5CH2. The benzoyl group is given the symbol "Bz". Benzyl is commonly abbreviated "Bn".

Sources[]

Benzoyl chloride is a favored source of benzoyl groups, being used to prepare benzoyl ketones, benzamides (benzoyl amides), and benzoate esters. The source of many naturally occurring benzoyl compounds is the thioester benzoyl-CoA. Irradiation of benzil generates benzoyl radicals, which have the formula PhCO.

Benzoyl compounds[]

Many ketones contain the benzoyl group. They have the formula C6H5CO–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. Benzoyl-β-D-glucoside is a natural substance that can be found in Pteris ensiformis.
