The direct and selective α-mono-bromination of alkylsulfones was achieved through base-mediated electrophilic halogenation. The appropriate combination of solvent and electrophilic bromine source was found to be critical to control the nature of the products formed, where reagent–solvent halogen bonding is proposed to control the selectivity via alteration of the effective size of the electrophilic
