A novel and efficient method for the selective synthesis of sulfinylated benzofulvenes has been developed through BF3 center dot Et2O-promoted electrophilic addition/cyclization of 1,3-enynes. This metal-free cascade reaction utilizes readily accessible arylsulfinic acids as sulfinyl cation sources at room temperature to provide a wide range of functionalized benzofulvenes in good to excellent yields under mild conditions.
