Allyyliryhmän
Allyyliryhmään, commonly referred to as the allyl group in English, is an organic functional group composed of a three-carbon chain with a terminal double bond (CH2=CH–CH2–). It is represented by the shorthand -CH2CH=CH2. The group is planar at the double bond, and the carbon atoms adjacent to the double bond are sp2 hybridized, while the terminal CH2 is sp3. Because of the conjugated π system, the allyl group can delocalize electron density, which influences its chemical behavior.
The allyl group is a common building block in organic synthesis, particularly in reactions that involve radical,
In organic chemistry, the presence of an allyl group alters the acidity of adjacent hydrogens and can
Because of its resonance stabilization, allyl compounds are relatively resistant to oxidation compared to other unsaturated
Overall, allyyliryhmään or the allyl group plays a vital role as a versatile and reactive scaffold in
