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]
Transition-metal allyl complexes are coordination complexes with allyl and its derivatives as ligands. Allyl is the radical with the connectivity CH 2 CHCH 2 , although as a ligand it is usually viewed as an allyl anion CH 2 =CH−CH 2 − , which is usually described as two equivalent resonance structures.

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]
Allyl halides are organic halides containing an allyl group. Allyl halides include: Allyl chloride; Allyl bromide; Allyl iodide; Allyl fluoride [Wikidata] See also.
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]
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
