The use of a new class of unsymmetrical cinchona‐alkaloid‐based, phthalazine‐bridged organocatalysts enabled the highly enantioselective dichlorination of unfunctionalized alkenes. In combination with the electrophilic chlorinating agent 1,3‐dichloro‐5,5‐dimethylhydantoin (DCDMH) and triethylsilyl chloride (TES‐Cl) as the source of nucleophilic chloride, 1‐aryl‐2‐alkyl alkenes were dichlorinated with enantioselectivities of up to 94:6er. Initial mechanistic investigations suggest that no free chlorine is formed, and by replacement of the chloride by fluoride, enantioselective chlorofluorinations of alkenes are possible.
