Cumene (isopropylbenzene) is an organic compound that contains a benzene ring with an isopropyl substituent. It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C.
This latter cumene converts into cumene radical and feeds back into subsequent chain formations of cumene hydroperoxides. A pressure of 5 atm is used to ensure that the unstable peroxide is kept in liquid state. Cumene hydroperoxide undergoes a rearrangement reaction in an acidic medium (the Hock rearrangement) to give phenol and acetone. In ...
Diisopropylbenzenes typically arise by alkylation of benzene or isopropylbenzene with propylene: C 6 H 6 + CH 3 CH=CH 2 → C 6 H 5 CH(CH 3) 2 C 6 H 5 CH(CH 3) 2 + CH 3 CH=CH 2 → C 6 H 4 (CH(CH 3) 2) 2. These alkylations are catalyzed by various Lewis acids, such as aluminium trichloride. They can also be prepared and transformed by ...

It is used commercially in perfumes and other cosmetics. It has been shown that cuminaldehyde, as a small molecule, inhibits the fibrillation of alpha-synuclein , [ 2 ] which, if aggregated, forms insoluble fibrils in pathological conditions characterized by Lewy bodies , such as Parkinson's disease , dementia with Lewy bodies [ 3 ] and ...
In addition to p-cymene, two less common geometric isomers are o-cymene, in which the alkyl groups are ortho-substituted, and m-cymene, in which they are meta-substituted.
