Ab initio and density functional calculations predict that intramolecular homolytic substitution reactions of oxyacyl radicals at the selenium atom in ω-alkylseleno-substituted radicals proceed via mechanisms that do not involve hypervalent intermed

The trimethylstannyl substituent raises the migratory aptitude of a primary β-carbon to be above that of a not otherwise activated secondary or tertiary carbon. This is apparent from the exclusive formation of the alkene acids 9–11 from Baeyer–V

Generation of the 5-(2'-deoxyuridinyl)methyl radical (6) was reexamined. Trapping by 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl confirms that 6 is generated. However, trapping by methoxyamine reveals that the respective carbocation (10) is also pr

There was a time when free radicals were scorned by organic chemists and when “practically every organic text book written” contained a statement that free radicals were “incapable of an independent existence”.
