Synthesis and crystal and molecular structure of μ-oxo-bis[trifluoroacetato(p-tolyl)iodine]

Remote Substituents as Potential Control Elements for the Solid-State Structures of Hypervalent Iodine(III) Compounds

“…The former are more relevant for structural comparisons here. Structural details for these four compounds are summarized along with details for 4c and 5d in Table . − The four reported μ- oxo-λ 3 -iodanes and 4c all feature extensive intermolecular bonding I···O interactions of varying degrees [structures C , D , and D′ (Figure )]. In structure type C , there are a pair of [I–O–I]···OC interactions that hold together a dimeric assembly of two molecules .…”

“…In structure type C , there are a pair of [I–O–I]···OC interactions that hold together a dimeric assembly of two molecules . In structure types D and D′ , one of the [I–O–I]···OC interactions involves a third molecule, thus forming a polymeric assembly in the solid state. − A weak I···FCF 2 interaction [3.38(9) Å] approximately trans to the I–C ipso bond in DAJTUD is present …”

“…80−83 The four reported μoxo-λ 3 approximately trans to the I−C ipso bond in DAJTUD is present. 83 Compound 5b, however, presents a completely new type of structure format. First, the crystals of 5b contain two independent molecules that differ mainly in the projection of the aryl units with respect to one another (highlighted in green in Figure 6).…”

Chemistry of xenon derivatives. Synthesis and chemical properties

“…Thus the reagent (6d) obtained in situ from XeF 2 and trifluoroacetic acid in the presence of trifluoroacetanhydride reacts with aryl iodides to give bis(trifluoroacetoxy)-l 3 -iodanylarenes 199 ± 201. 357 In the absence of trifluoroacetanhydride, this reaction affords m-oxobis-[trifluoroacetato(aryl)] iodides (202) the structure of which was established by X-ray diffraction analysis. 357,358 A one-step procedure for the generation of iodanylarenes directly from aryl iodides 359 ± 367 is based on their oxidation by xenon fluorosulfonate which gives salts of the type 203.…”
