Journal ArticleDOI
Thermochemical parameters for organic radicals and radical ions. Part 1. The estimation of the pKa of radical cations based on thermochemical calculations
TL;DR: In this paper, three methods for estimating the pKa of a radical cation using thermochemical cycles are discussed, which enable the calculations of the pK of radical cations which have not yet been determine.
Journal ArticleDOI
Radical ions in photochemistry. 5. photosensitized (electron transfer) cyanation of olefins
Journal ArticleDOI
Photochemical nucleophile-olefin combination, aromatic substitution reaction. Its synthetic development and mechanistic exploration.
Dino Mangion,Donald R. Arnold +1 more
TL;DR: An overview of the mechanistic exploration and rationalization of this photoinduced electron transfer reaction is presented and the synthetic scope and limitations by variations in reaction conditions and structural modification of the substrates are defined.
Journal ArticleDOI
Radical ions in photochemistry. 6. The photosensitized (electron transfer) ring opening of aryloxiranes
Angelo Albini,Donald R. Arnold +1 more
TL;DR: The photosensitized (electron transfer) irradiation of cis- and trans-2,3-diphenyloxirane (1 and 2) led to cleavage of the oxirane carbon-carbon bond and subsequent formation of the carbonyl ylide as mentioned in this paper.
Journal ArticleDOI
Radical ions in photochemistry. 15. The photosubstitution reaction between dicyanobenzenes and alkyl olefins
TL;DR: The photosubstitution (electron transfer) reaction between 1,4-dicyanobenzene (1) and 2,3-dimethyl-2-butene (2) as discussed by the authors gave 1-(4-cyanophenyl)-2,3 -dimethyl 2-butenes (3) and 3-(4]-cyan-phenyl 2-3-di...
