Reduction of intermolecular association in the sterically encumbered (dichloroiodo)arene ArICl2[Ar = 2,6-bis(3,5-dichloro-2,4,6-trimethylphenyl)benzene]

Abstract

The synthesis of the sterically encumbered (dichloroiodo)arene ArICl₂[Ar = 2,6-bis(3,5-dichloro-2,4,6-trimethyl-phenyl)benzene] is achieved via a novel hexachlorination reaction and an X-ray structural determination reveals a reduced intermolecular association for the hypervalent iodine species as compared to the only other crystallographically characterized (dichloroiodo)arene PhICl₂(the structure of which is re-examined in light of the present data).
