Allylbenzene or 3-phenylpropene is an organic compound with the formula C6H5CH2CH=CH2. It is a colorless liquid. The compound consists of a phenyl group attached to an allyl group. Allylbenzene isomerizes to trans-propenylbenzene.[1]
In plant biochemistry, the allylbenzene skeleton is the parent (simplest representation) of many phenylpropanoids. Prominent allylbenzenes include eugenol, safrole, and many others.[2]
