It is not a coincidence that both chirality and noncovalent interactions are ubiquitous in
nature and synthetic molecular systems. Noncovalent interactivity between chiral molecules …

Transition metal catalysis is of utmost importance for the development of sustainable
processes in academia and industry. The activity and selectivity of metal complexes are …

Understanding the noncovalent interactions (NCIs) among the residues of proteins and
nucleic acids, and between drugs and proteins/nucleic acids, etc., has extraordinary …

In this review, we provide a consistent description of noncovalent interactions, covering most
groups of the Periodic Table. Different types of bonds are discussed using their trivial …

In the last few decades,“unusual” noncovalent interactions like anion‐π and halogen
bonding have emerged as interesting alternatives to the ubiquitous hydrogen bonding in …

The chalcogen bond (ChB) is defined as a noncovalent interaction between the electron
density deficient region (so-called as σ or π hole) of a covalently bonded chalcogen atom …

Conspectus The exploration of new catalysis concepts and strategies to drive chemical
reactions is of vital importance for the sustainable development of organic synthesis …

A covalently-bonded atom typically has a region of lower electronic density, a “σ-hole,” on
the side of the atom opposite to the bond, along its extension. There is frequently a positive …

Sigma (σ)-holes are electron-deficient regions that arise from the anisotropic distribution of
electron density on the atom of group 14 (tetrels), 15 (pnictogens), 16 (chalcogens), and 17 …

The σ-hole and π-hole are the regions with positive surface electrostatic potential on the
molecule entity; the former specifically refers to the positive region of a molecular entity …
