Allyl alcohol (IUPAC name: prop-2-en-1-ol) is an organic compound with the structural formula CH 2 =CHCH 2 OH. Like many alcohols, it is a water-soluble, colourless liquid. It is more toxic than typical small alcohols. Allyl alcohol is used as a precursor to many specialized compounds such as flame-resistant materials, drying oils, and ...
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 .

The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
An allylic rearrangement or allylic shift is an organic chemical reaction in which reaction at a center vicinal to a double bond causes the double bond to shift to an adjacent pair of atoms: It is encountered in both nucleophilic and electrophilic substitution , although it is usually suppressed relative to non-allylic substitution.
Diallyl carbonate can be synthesized by consecutive nucleophilic acyl substitution reactions using two equivalents of allyl alcohol and any of several electrophilic carbonyl donors. The monoallyl intermediate can be isolated and then separately converted to the diallyl product, or the whole process can be run in a single reactor.
In allyl lithium compounds, the lithium cation coordinates to the face of the carbon π bond in an η 3 fashion instead of a localized, carbanionic center, thus, allyllithiums are often less aggregated than alkyllithiums. [6] [12] In aryllithium complexes, the lithium cation coordinates to a single carbanion center through a Li−C σ type bond ...
An enone forms an allylic alcohol in a 1,2-addition, and the competing conjugate 1,4-addition is suppressed. The selectivity can be explained in terms of the HSAB theory: carbonyl groups require hard nucleophiles for 1,2-addition. The hardness of the borohydride is increased by replacing hydride groups with alkoxide groups, a reaction catalyzed ...
