Theoretical studies replace double bonds with dative in hypervalent iodine compounds

Hypervalent iodine reagents are widely used in organic synthesis, but their structures haven’t been studied in detail. In the majority of textbooks and papers, they are drawn with double bonds between iodine and oxygen, nitrogen or carbon.

But a new study has used theoretical models to show that this might be incorrect. Instead, it suggests the bonds within some of these compounds are dative, with iodine donating the electron pair.
