DOI: 10.1021/acsomega.0c03000
Abstract: It is found by experiment that the cationic halogen bond donors (cationic iodoimidazolium compounds) can activate the Ritter-type solvolysis of benzhydryl bromide, while the cationic hydrogen bond donors (cationic imidazolium compounds) could not. To understand… read more here.

DOI: 10.1021/jacs.9b13309
Abstract: “Hypervalent” iodine(III) derivatives have been established as powerful reagents in organic transformations, but so far only a handful of studies have addressed their potential use as halogen-bonding noncovalent Lewis acids. In contrast to “classical” halogen-bond… read more here.

DOI: 10.1039/c8ce00945g
Abstract: The supramolecular interactions between 1,3-bis(4-pyridyl)azulene (azbbpy) as a hydrogen bond acceptor and a variety of aromatic hydrogen-bond donors produced new binary molecular co-crystals and a salt. All crystal structures display extensive and very complex hydrogen… read more here.

DOI: 10.1039/d3cc00371j
Abstract: We report the use of nitrone C-H groups as hydrogen bond donors for binding anions. Acyclic anion receptors with two nitrone moieties were synthesized by condensation reactions between aryl-aldehydes and m-phenylenedihydroxylamines. The solid-state structure of… read more here.
