Benzocyclanones were mono- or dihalogenated on the aromatic ring with elemental halogen or N-halosuccinimide without solvent in an aluminum chloride slurry in good yield. This process is the most direct method for the synthesis of 5- or 7-halo, or 5,7-dihalotetralones and can be extended to indan-1-ones and benzocycloheptan-1-ones as well as to trihalogenated and to mixed halogenated products.
