Silica gel-mediated hydrochlorination of unactivated alkenes using 35% hydrochloric acid underorganicsolvent-freeconditions proceeded to give the corresponding chlorides in good yields. Hydrobromination or hydriodination using 47% hydrobromic acid or 55% hydriodic acid afforded the corresponding halides, respectively. Silica gel could be recycled five times without any significant loss of activities
