In organic chemistry, 1-propenyl (or simply propenyl) has the formula CH=CHCH3 and 2-propenyl (isopropenyl) has the formula CH2=C-CH3.
These groups are found in many compounds.
Propenyl compounds are isomeric with allyl compounds, which have the formula CH2-CH=CH2.
Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene: Isopropenyl acetate is a 2-propenyl ester, synthesizable from ketene.
Several terpenes feature 2-propenyl substituents: This organic chemistry article is a stub.
