Reaction mechanisms: radical and radical ion reactions

Electrifying green synthesis: recent advances in electrochemical annulation reactions

“…Due to its high reactivity and practical tolerance, it provided motivation for the development of new synthetic methodologies. 121 Currently, several methods for obtaining radical carbons are known, e.g. using halides, carboxylic acids, borates, alcohols, and silicates, metal catalysis, photoredox catalysis, ultrasound, microwaves, and electrochemistry, among others.…”

Rovibronic Spectroscopy of Sympathetically Cooled 40CaH+

“…A. 1 The experimental rovibronic frequency along with the associated assignment for each transition. Repeated values are due to unresolved P and R branches.…”

“…. reaction mechanisms such as ionic reactions in organic chemistry [1,2] or the reactions proposed to occur in space [3,4]. Ion traps provide an isolated environment for the creation and study of reactive species whose spectra are lacking compared to their neutral counterparts.…”

“…In addition, the of full quantum controlled chemistry provides insight into the details of non-Arrhenius behavior such as tunneling and submerged barriers that may influence reaction kinetics at low temperatures and densities. Aside from astrochemistry, these ion-molecule reactions are important in understanding the fundamental processes underlying practical applications like plasma etching [55] and reactions in organic chemistry [1,2]. As important as the reactions are to organic chemistry in the identification of reaction pathways and predicting yields [2], this class of reactions has limited studies at the fundamental level [56].…”

An Air-Stable Alkene-Derived Organic Radical Cation

“…Organic open-shell compounds such as radicals and radical ions (cations or anions) comprise an important class of compounds due to their various applications from synthetic chemistry to various branches of materials science . However, most organic radicals and radical ions are highly reactive toward an open atmosphere and must be handled under inert atmosphere conditions, which restricts their utilization . The design and synthesis of air-stable radicals and radical ions are therefore generally attractive but challenging.…”
