Abstract

A group of para-substituted bis(acetoxy)iodoarenes has been studied by 17O and 13C NMR. Only one signal for all the oxygens of the acetoxy groups has been observed. Both 17O and 13C chemical shifts of this group show a strong invariance with para substitution. The absence of covalent I–O bonds and an ion pair structure is proposed for the title compounds
