A Radical Mechanism for Frustrated Lewis Pair Reactivity [PDF]

Chem, 2017
Summary The frustrated Lewis pairs (FLPs) derived from t Bu 3 P and E(C 6 F 5 ) 3 (E = B, Al) react with p O 2 C 6 Cl 4 and Ph 3 SnH to give [ t Bu 3 POC 6 Cl 4 OE(C 6 F 5 ) 3 ] (E = B 1 , Al  2 ), [ t Bu 3 PSnPh 3 ][HB(C 6 F 5 ) 3 ] 3 , and [ t Bu 3 PSnPh 3 ][(μ-H)(Al(C 6 F 5 ) 3 ) 2 ] 4 .

Radio Frequency Magnetic Field Effects on a Radical Recombination Reaction:  A Diagnostic Test for the Radical Pair Mechanism

Journal of the American Chemical Society, 2004
The photoinduced electron-transfer reaction of chrysene with isomers of dicyanobenzene is used to demonstrate the sensitivity of a radical recombination reaction to the orientation and frequency (5-50 MHz) of a approximately 300 muT radio frequency magnetic field in the presence of a 0-4 mT static magnetic field. The recombination yield is detected via

The Role of Pulsed Electromagnetic Fields on the Radical Pair Mechanism [PDF]

Bioelectromagnetics, 2021
In recent decades, the use of pulsed electromagnetic fields (PEMF) in therapeutics has been one of the main fields of activity in the bioelectromagnetics arena. Nevertheless, progress in this area has been hindered by the lack of consensus on a biophysical mechanism of interaction that can satisfactorily explain how low‐level, non‐thermal ...

Hypomagnetic field effects as a potential avenue for testing the radical pair mechanism in biology

Frontiers in Physics, 2023
Near-zero magnetic fields, called hypomagnetic fields, are known to impact biological phenomena, including developmental processes, the circadian system, neuronal and brain activities, DNA methylation, calcium balance in cells, and many more.

Radical pairs may explain reactive oxygen species-mediated effects of hypomagnetic field on neurogenesis.

PLoS Computational Biology, 2022
Exposures to a hypomagnetic field can affect biological processes. Recently, it has been observed that hypomagnetic field exposure can adversely affect adult hippocampal neurogenesis and hippocampus-dependent cognition in mice.

Radical pairs may play a role in microtubule reorganization

Scientific Reports, 2022
The exact mechanism behind general anesthesia remains an open question in neuroscience. It has been proposed that anesthetics selectively prevent consciousness and memory via acting on microtubules (MTs).

Radical pairs may play a role in xenon-induced general anesthesia

Scientific Reports, 2021
Understanding the mechanisms underlying general anesthesia would be a key step towards understanding consciousness. The process of xenon-induced general anesthesia has been shown to involve electron transfer, and the potency of xenon as a general ...

Quantum Sensing and Control of Spin-State Dynamics in the Radical-Pair Mechanism [PDF]

Physical Review Applied, 2021
Radical pairs and the dynamics they undergo are prevalent in many chemical and biological systems. Specifically, it has been proposed that the radical pair mechanism results from a relatively strong hyperfine interaction with its intrinsic nuclear spin environment.
