Halogenation of Alkyl p-Tolyl Sulfones with Carbon Tetrahalides. Application to the Synthesis of Aromatic Ketones

Article abstract of DOI:10.1246/bcsj.53.3027

Carbanions of alkyl p-tolyl sulfones reacted with carbon tetrahalides to give the corresponding polyhalogenated products in good yields.Some chlorinated sulfones were converted to unsymmetrical ketones by treatment with silver perchlorate in trifluoroacetic acid.
