When the tricyclic isolongifolene 2 is exposed to HX(HBr, HI) in AcOH, a unique ring fragmentation takes place resulting in the formation of a novel bicyclic monoolefinic primary halide 9/10. The closely related tetracyclic cyclopropane isomer 14 of the tricyclicolefin 2, on reaction with HI in AcOH, also affords 10. Attempted solvolysis of 9 with AgClO4 in 50% aqueous acetone generates essentially
