Neohexene is the hydrocarbon compound with the chemical formula . It is a colorless liquid, with properties similar to other hexenes. It is a precursor to commercial synthetic musk perfumes.
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.
