A haloketone in organic chemistry's a functional group consisting of a ketone group or more general a carbonyl group with a α-halogen substituent. The general structure's RR'C(X)C(=O)R where R's an alkyl or aryl residue and X any one of the halogens. The preferred conformation of a haloketone's that of a cisoid with the halogen and carbonyl sharing the same plane as the steric hindrance with the carbonyl alkyl group's generally larger .
