Propenyl

From Wikipedia, the free encyclopedia

Inorganic chemistry,1-propenyl (or simplypropenyl) has the formula CH=CHCH3 and2-propenyl (isopropenyl) has the formula CH2=C-CH3. These groups are found in many compounds. Propenyl compounds are isomeric withallyl compounds, which have the formula CH2-CH=CH2.

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

Chemicals with 1-propenyl groups

[edit]

Manyphenylpropanoids and their derivatives feature derivatives of propenylbenzene:

Chemicals with 2-propenyl groups

[edit]
p-Isopropenylphenol features a 2-propenyl derivative ofphenol.

Isopropenyl acetate is a 2-propenylester, synthesizable fromketene.

Severalterpenes feature 2-propenyl substituents:
