Phenacyl group
# Phenacyl group

In organic chemistry, a phenacyl group is an aromatic substituent that consists of a phenyl group attached to an acyl group. A molecule containing a phenacyl group has the formula $RCH_2(CO)C_6H_5$ and the structure shown to the right. Here, R denotes the remainder of the molecule; for instance, if R is Br, then the compound could be called "phenacyl bromide". Note however that in the standard IUPAC nomenclature this compound would instead be called "2-bromo-1-phenylethanone".

## Examples

* Phenacyl chloride is also known as CN gas.
* Phenacyl bromide, a toxic chemical mainly used in the production of other chemicals.
