Radical Reactions

Radical Halogenation

Produces Markovnikov alkyl halide to add X at a stable carbocation and if producing a chiral center it will produce the enantiomer but if a chiral center is already present it will produce the diasteomer

Radical Hydrohalogenation

Produces anti-markovnikov alkyl halide using HBr and H2O2

Allylic Bromination

Uses NBS or NCS to add Br or Cl and produces a chiral center with an enantiomer

Homolytic Cleavage

Breaks X2 to create two radicals

Addition to a pi bond

Destroys a pi bond creating a new radical and sigma bond

Hydrogen Abstraction

H is removed to attach to a radical and in turns forms another radical

Halogen Abstraction

X is removed to attach to a radical and in turns forms another radical

Elimination

A pi bond is made using a radical and breaking a sigma bond with it being in the location of the radical and an unpaired radical

Coupling

Two radicals join together

Initiation

radicals are created

Propagation

location of radical is moved

Termination

Two radicals join together at the end to form a bond
