2,6-Dichloroiodobenzene, also known as 1,3-dichloro-2-iodobenzene, is a halo-substituted benzene. It couples with 1,1′-diaminoferrocene in the presence of a palladium catalyst to form substituted diamide ligands (Fc(NHAr)₂).

2,6-Dichloroiodobenzene may be used in the preparation of 2,6-dichlorobenzo[¹⁴C]nitrile and 2,6-terphenyl carboxylic acid ligands.
It may be used as a starting material in the multi-step synthesis of:

• cupped oxacyclophanes
• cuppedophanes
• cappedophanes
• m-terphenyls
