Allylic

Definition

In organic chemistry, an allylic position refers to the next carbon atom adjacent to a double bond in an alkene. This position is significant due to its unique reactivity, particularly in the context of allylic bromination where it can be selectively halogenated.

Related terms

Alkene:

A hydrocarbon that contains at least one carbon-carbon double bond, which plays a critical role in the structure and reactivity of organic molecules.

Bromination:

A chemical reaction involving the addition of bromine (Br2) across a double bond or at an allylic position, leading to the formation of brominated organic compounds.

Halogenation:

A chemical reaction that involves the addition of halogens (like fluorine, chlorine, bromine, or iodine) to another substance, commonly used for synthesizing alkyl halides from alkenes or other precursors
