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 aprotecting group
A protecting group or protective group is introduced into a molecule by chemical modification of a functional group to obtain chemoselectivity in a subsequent chemical reaction. It plays an important role in multistep organic synthesis.
