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.

Chemicals with 1-propenyl groups
edit- 2-chloropropylene
- propenylbenzene (β-methylstyrene).[1]
Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene:
Chemicals with 2-propenyl groups
editIsopropenyl acetate is a 2-propenyl ester, synthesizable from ketene.
Several terpenes feature 2-propenyl substituents:
