Structure of the allyl group. In organic chemistry, an allyl group is a substituent with the structural formula −CH 2 −HC=CH 2. It consists of a methylene bridge (−CH 2 −) attached to a vinyl group (−CH=CH 2). [1] [2] The name is derived from the scientific name for garlic, Allium sativum.

Allyl alcohol is converted mainly to glycidol, which is a chemical intermediate in the synthesis of glycerol, glycidyl ethers, esters, and amines. Also, a variety of polymerizable esters are prepared from allyl alcohol, e.g. diallyl phthalate. [5] Allyl alcohol has herbicidal activity and can be used as a weed eradicant [9]) and fungicide. [8]
Chavicol is formed in sweet basil (Ocimum Basilicum) by the phenylpropanoid pathway via p-coumaryl alcohol.The allylic alcohol in p-coumaryl alcohol is converted into a leaving group.
All three allylamines, mono-, di-, and triallylamine, are produced by the treating allyl chloride with ammonia followed by distillation. [3] Or by the reaction of allyl chloride with hexamine. [4] Pure samples can be prepared by hydrolysis of allyl isothiocyanate. [5] It behaves as a typical amine. [6]
Allyl thiocyanate isomerizes to the isothiocyanate: [8] CH 2 =CHCH 2 SCN → CH 2 =CHCH 2 NCS. Allyl isothiocyanate can also be liberated by dry distillation of the seeds. The product obtained in this fashion is known as volatile oil of mustard. It is used principally as a flavoring agent in foods.
The Krische allylation involves “transfer hydrogenative” carbon-carbon bond formations. [16] In a series of papers published in the early 2000s, Krische and coworkers demonstrated that allenes, dienes, and allyl acetates could be converted to transient allylmetal nucleophiles via hydrogenation, transfer hydrogenation or hydrogen auto-transfer. [17]
