Propenyl
# Propenyl

In organic chemistry, 1-propenyl (or simply propenyl) has the formula $CH=CHCH_3$ and 2-propenyl (isopropenyl) has the formula $CH_2=C-CH_3.$ These groups are found in many compounds. Propenyl compounds are isomeric with allyl compounds, which have the formula $CH_2-CH=CH_2.$

## Chemicals with 1-propenyl groups

* 2-chloropropylene
* propenylbenzene (β-methylstyrene).

Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene:

* Anethole
* Asarone
* Carpacin
* Coniferyl alcohol
* Isoeugenol
* Isosafrole
* Methyl isoeugenol
* Pseudoisoeugenol

## Chemicals with 2-propenyl groups

Several terpenes feature 2-propenyl substituents:

* carvone
* limonene
