This review sets out to understand the reactivity of diradicals and how that may differ from
monoradicals. In the first part of the review, we delineate the electronic structure of a …

Analogies between the mechanisms of electrophilic substitution and nucleophilic
substitution have been discussed. Theoretical calculations, involving aromaticity …

Coupling of the radical sites in isomeric benzynes is known to hinder their radical reactivity.
In order to determine how far apart the radical sites must be for them not to interact, the gas …

The gaseous 2, 6-didehydropyridinium cation and its derivatives transfer a proton to
reagents for which the reaction for their singlet ground states is too endothermic to be …

The reactivity of a carbon‐centered σ, σ, σ, σ‐type singlet tetraradical containing two meta‐
benzyne moieties, the 2, 4, 5, 7‐tetradehydroquinolinium cation, was examined in the gas …

The gas-phase reactivities of several protonated quinoline-based σ-type (carbon-centered)
mono-, bi-, and triradicals toward dimethyl disulfide (DMDS) were studied by using a linear …

Examination of the reactions of σ‐type quinolinium‐based triradicals with cyclohexane in the
gas phase demonstrated that the radical site that is the least strongly coupled to the other …
