Neohexene is the hydrocarbon compound with the chemical formula (CH3)3CCH=CH2. It is a colorless liquid, with properties similar to other hexenes. It is a precursor to commercial synthetic musk perfumes.
Preparation and reactions
[edit | edit source]Neohexene is prepared by ethenolysis of diisobutene, an example of a metathesis reaction:[1]
- (CH3)3C-CH=C(CH3)2 + CH2=CH2 → (CH3)3C-CH=CH2 + (CH3)2C=CH2
It is a building block to synthetic musks by its reaction with p-cymene. It is also used in the industrial preparation of terbinafine.[1]
In the study of C-H activation, neohexene is often used as a hydrogen acceptor.[2]
