Allyl

In chemistry, the allyl (or allyl group) is a functional group corresponding to a propylene deprived of a hydrogen atom, having formula:

CH2=CH-CH2

This functional group causes a resonance phenomenon, which gives it greater stability. Compounds containing an allyl are called allyl compounds. Examples of compounds containing the allyl group are:

  • allyl sulfide
  • allyl isothiocyanate
  • diallyl disulfide
  • allyl alcohol

Allyl oxidation

In organic compounds with a double bond, the carbon atoms adjacent to the double bond are usually easily attacked by different oxidizing agents. The oxidation of these positions of the molecule, comparable to the -CH2– group of the allyl radical, is called allyl oxidation. Allyl oxidation is of technical importance, among other things, in the rancidity processes of vegetable oils, in which it leads to the attack of the allyl positions of double-bonded fatty acids.
