  2. Allyl group - Wikipedia

    en.wikipedia.org/wiki/Allyl_group

    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 ]

  4. Allylic rearrangement - Wikipedia

    en.wikipedia.org/wiki/Allylic_rearrangement

    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.

  6. Transition-metal allyl complex - Wikipedia

    en.wikipedia.org/wiki/Transition-metal_allyl_complex

    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.

  7. Krische allylation - Wikipedia

    en.wikipedia.org/wiki/Krische_allylation

    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 ...

  8. Diallyl carbonate - Wikipedia

    en.wikipedia.org/wiki/Diallyl_carbonate

    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.

  9. Organyl group - Wikipedia

    en.wikipedia.org/wiki/Organyl_group

    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.
