Abstract
Addition of halogens (Cl2, Br2) and pseudo-halogens (ICl, halogen azides, NOCl) to solongifolene does not yield any "normal" addition products due to severe steric hindrance to the approach of counter ion at C-7. Initially formed halogenonium ions undergo elimination or rearrangement to give "abnormal" products. The term Steric Diversion is suggested to describe this switch over from the "normal" route.
