This electrophilic intermediate may be attacked by a variety of nucleophiles or undergo rearrangement or elimination.

The initially formed cyclopropane undergoes a ring expansion and subsequent elimination of hydrogen fluoride.

This forms the aryl-palladium-heteroatom intermediate, which undergoes reductive elimination to form the final heteroaromatic compound.

This intermediate then undergoes reductive elimination, coupling the aryl to the carbon-3 position of the heteroatom.

Conversely, complexes of 18 electron configuration tend to dissociate ligands or undergo reductive elimination:

In the final step, complex D undergoes reductive elimination to produce the alkyne, with regeneration of the palladium catalyst.

Compound 3 undergoes elimination to produce the thionium ion 4.

Sulfones with a good leaving group in the β position may undergo reductive elimination under desulfonylation conditions to afford alkenes.

Toluenesulfonate esters undergo nucleophilic attack or elimination.

The acylimine acceptors were generated in situ from α-tosylamide substrates, which underwent elimination in the presence of base.
