From Wikipedia, the free encyclopedia

In organic chemistry, 1-propenyl (or simply propenyl) has the formula ·CH=CH–CH3 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.

The three common precursors to lignin are derivatives of propenylbenzene: paracoumaryl alcohol (1), coniferyl alcohol (2) and sinapyl alcohol (3).

Chemicals with 1-propenyl groups

Many phenylpropanoids and their derivatives feature derivatives of propenylbenzene:
