Propenyl

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
Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene:
 * 2-chloropropylene
 * propenylbenzene (β-methylstyrene).
 * Anethole
 * Asarone
 * Carpacin
 * Coniferyl alcohol
 * Isoeugenol
 * Isosafrole
 * Methyl isoeugenol
 * Pseudoisoeugenol

Chemicals with 2-propenyl groups
Isopropenyl acetate is a 2-propenyl ester, synthesizable from ketene.

Several terpenes feature 2-propenyl substituents:
 * carvone
 * limonene
