Non‐covalent molecular interactions on the basis of halogen and chalcogen bonding
represent a promising, powerful catalytic activation mode. However, these “unusual” non …

The halogen bond is a supramolecular interaction between a Lewis‐acidic region of a
covalently bound halogen and a Lewis base. It has been studied widely in silico and …

Halogen bonding, the noncovalent interaction based on electrophilic halogen substituents,
features very interesting properties, as illustrated by numerous applications continuously …

Chalcogen bonding is the non‐covalent interaction between Lewis acidic chalcogen
substituents and Lewis bases. Herein, we present the first application of dicationic tellurium …

In contrast to iodine (I)‐based halogen bond donors, iodine (III)‐derived ones have only
been used as Lewis acidic organocatalysts in a handful of examples, and in all cases they …

Hypervalent iodine (III) derivatives are known as versatile reagents in organic synthesis, but
there is only one previous report on their use as Lewis acidic organocatalysts. Herein, we …

Molecular iodine has been used for more than 100 years as a remarkable catalyst for many
organic transformations such as cycloadditions, Michael and aldol reactions, or …

Dibenziodolium and diphenyliodonium triflates display high catalytic activity for the
multicomponent reaction that leads to a series of imidazopyridines. Density functional theory …

Noncovalent interactions like halogen, chalcogen, and pnictogen bonding are known for a
very long time. During the last decade, these interactions have found different applications in …

In the last years the use of chalcogen bonding—the noncovalent interaction involving
electrophilic chalcogen centers—in noncovalent organocatalysis has received increased …
