Summary
This review clarifies the distinct properties of pi-mers and pi-dimers, radical interactions often confused in scientific literature. Understanding their differences is crucial for predicting system behavior.
Area of Science:
- Physical Chemistry
- Supramolecular Chemistry
- Radical Chemistry
Background:
- Pi-mers (pimers) and pi-dimers (pi-dimers) are radical interactions frequently interchanged in scientific literature.
- These interactions exhibit distinct and sometimes opposing physico-chemical behaviors.
- Lack of clear distinction hinders accurate interpretation of experimental results.
Purpose of the Study:
- To differentiate between pi-mers and pi-dimers.
- To elucidate the unique physico-chemical properties of each species.
- To provide a clear reference for researchers working with these radical interactions.
Main Methods:
- Literature review and synthesis of existing research.
- Comparative analysis of physico-chemical properties.
- Case studies illustrating sequential formation and property changes.
Main Results:
- Pi-mers and pi-dimers possess fundamentally different structural and electronic characteristics.
- Their distinct properties lead to divergent behaviors in various chemical systems.
- Conversion between pi-mers and pi-dimers results in significant physico-chemical alterations.
Conclusions:
- Accurate identification and differentiation of pi-mers and pi-dimers are essential.
- Understanding these differences allows for better prediction and control of chemical processes.
- This review provides a foundation for resolving ambiguities in the literature regarding these radical species.

1.9K
The presence of electron-donating, electron-withdrawing, or conjugating groups adjacent to a radical center, imparts electronic stabilization to the radicals. Examples of such electronically-stabilized radicals are triphenylmethyl, tetramethylpiperidine‐N‐oxide, and 2,2‐diphenyl‐1‐picrylhydrazyl. These radicals are remarkably stable and are known as persistent radicals. Some of the persistent radicals can even be isolated and purified.

01:11Radical Reactivity: Overview
2.1K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

01:17Electron Paramagnetic Resonance (EPR) Spectroscopy: Organic Radicals
2.4K
Ideally, an unpaired electron shows a single peak in the EPR spectrum due to the transition between the two spin energy states. However, coupling interactions can occur between the spins of the unpaired electron and any neighboring spin-active nuclei. This hyperfine coupling results in hyperfine splitting, where the EPR signal is split into multiplets. The signals split into 2nI + 1 peaks, where n is the number of equivalent nuclei and I is the nuclear spin. These splitting patterns provide...

01:27π Molecular Orbitals of the Allyl Radical
3.4K
Allyl radicals are three-carbon conjugated systems. They are readily formed as intermediates in halogenation reactions of alkenes involving the addition of halogen to the allylic carbon instead of the double bond. As seen in allyl cations and anions, each of the three sp2-hybridized carbon atoms in allyl radicals has an unhybridized p orbital. These orbitals combine to give three π molecular orbitals.
The allyl systems have identical molecular orbitals but differ in the number of π electrons....

This lesson delves into the geometry of a radical, which is influenced by the electronic structure of the molecule. The principle is similar to that of a lone pair, where the unpaired electron influences the geometry at the radical center.
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
