Reactive Intermediates in Radical Reactions

These flashcards cover important terms and concepts associated with radical chemistry and reactions, based on lecture notes.

Radical

A species with an unpaired electron, highly reactive.

Chain Initiation

The first step in radical reactions where radicals are generated.

Chain Propagation

The steps in a radical reaction where the radical reacts to form a new radical.

Chain Termination

The step in a radical reaction where radicals combine to form stable products, stopping the reaction.

Tributyltin hydride (Bu3SnH)

A radical initiator used in various radical reactions.

Allylic Bromination

A radical reaction that introduces a bromine atom to an allylic position, typically using NBS.

Benzylic Bromination

A radical reaction similar to allylic bromination but involving benzylic positions.

Bouveault-Blanc Reduction

A reaction that utilizes dissolving metals to create radical anions in protic solvents.

AIBN

Azobisisobutyronitrile, a common radical initiator.

Radical Addition

A reaction mechanism where radicals add to alkenes or alkynes.

Xanthate

A type of thiocarbonate used in radical reductions, particularly in the Barton McCombie reaction.

Initiation Stage

The phase in a radical reaction where initiation occurs, leading to the formation of radicals.
