The allyl group is widely encountered in organic chemistry. [1] Allylic radicals , anions , and cations are often discussed as intermediates in reactions . All feature three contiguous sp²-hybridized carbon centers and all derive stability from resonance. [ 6 ]

Allylic shifts become the dominant reaction pathway when there is substantial resistance to a normal (non-allylic) substitution. For nucleophilic substitution, such resistance is known when there is substantial steric hindrance at or around the leaving group, or if there is a geminal substituent destabilizing an accumulation of positive charge.

The allyl ligand is commonly in organometallic chemistry.Usually, allyl ligands bind to metals via all three carbon atoms, the η 3-binding mode.The η 3-allyl group is classified as an LX-type ligand in the Green LXZ ligand classification scheme, serving as a 3e – donor using neutral electron counting and 4e – donor using ionic electron counting.
The excellent functional group compatibility of the Krische allylation combined with the tractability of the allyl acetate pronucleophiles enables the use of allyl donors bearing highly complex nitrogen-rich substituents. [20] insert a caption here. The figure below shows some of the different allyl donors that have been used in the Krische ...
Its structure contains allyl groups and a functional carbonate group. [1] The presence of double bonds in the allyl groups makes it reactive in various chemical processes. This compound plays a key role in the production of polymers, including polycarbonates and polyurethanes.
In organic and organometallic chemistry, an organyl group is an organic substituent with one (sometimes more) free valence(-s) at a carbon atom. [1] The term is often used in chemical patent literature to protect claims over a broad scope.
