Preparation and reactions

Neohexene is prepared by ethenolysis of diisobutene, an example of a metathesis reaction:
It is a building block to synthetic musks by its reaction with p-cymene. It is also used in the industrial preparation of terbinafine.
In the study of C-H activation, neohexene is often used as a hydrogen acceptor.
