Controlled oxidation of enolates to α-carbonyl radicals and α-carbonyl cations
Abstract
Depending on the oxidation strength of the one-electron oxidants either persistent α-carbonyl radicals or α-carbonyl cation derived benzofurans are formed from enolates A1–A6, a result which can readily be rationalized by the measured oxidation potentials of enolates A1–A6and α-carbonyl radicals R1–R6.
