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
  • 2-chloropropylene
  • propenylbenzene (β-methylstyrene).[1]

Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene:

  • 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
