Summary
Frustrated Lewis pairs (FLPs) are versatile chelating ligands, stabilizing reactive species through cooperative Lewis acid-base interactions. This review explores their application in main group element chemistry across p-block groups 13-16.
Area of Science:
- Inorganic Chemistry
- Organometallic Chemistry
- Main Group Chemistry
Background:
- Frustrated Lewis pairs (FLPs) are extensively studied for small molecule activation.
- Intramolecular FLPs are emerging as promising chelating ligands.
- FLPs utilize cooperative Lewis acid-base interactions to stabilize reactive species.
Purpose of the Study:
- To review the current state of intramolecular FLP chelation.
- To cover FLP applications across p-block groups 13-16.
- To highlight the donor-acceptor stabilization mechanism.
Main Methods:
- Literature review of FLP chelation studies.
- Analysis of FLP coordination in main group elements.
- Focus on Lewis acid-base cooperative effects.
Main Results:
- Intramolecular FLPs effectively chelate to main group elements.
- Stabilization of low oxidation states and reactive fragments is achieved.
- Diverse applications in groups 13-16 are demonstrated.
Conclusions:
- Intramolecular FLPs represent a significant ligand class in main group chemistry.
- Their chelating ability offers unique stabilization pathways.
- Further exploration across the p-block is warranted.

Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

Lewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures—drawings that describe the bonding in molecules and polyatomic ions. The periodic table can be used to predict the number of valence electrons in an atom and the number of bonds that will be formed to reach an octet. Group 18 elements, such as argon and helium, have filled electron configurations and thus rarely participate in chemical bonding. However, atoms from group 17, such as...

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.
