Allyl

Allyl group as an unsaturated hydrocarbon group is known in the organic chemistry, which has the formula H2C = CH -CH2- has therefore represents a 2-propenyl group. It is formally a vinyl group H2C = CH-, to which a methyl group -CH 2- attached. Allyl- and cations are resonance-stabilized radicals, and therefore considerably more stable than the corresponding tert- butyl cation or radical. For example, allyl alcohol, the formula H2C = CH- CH2 -OH.

The term was coined in 1844 by allyl Theodor Wertheim and is derived from Allium, Latin for garlic in which there are a number of allyl compounds such as allicin.

Properties and Uses

The allyl group is due to the easy abstractability one of the allyl position, ie sp3 -hybridized, the double bond adjacent carbon atom bonded hydrogen atoms or protons a reactive functional group in organic molecules. There are also two different substituents other tied, the occurring due to the 1,3 -allylic strain unique orientation of the groups can be exploited to each other in stereoselective synthesis.
