[41] Shortly after, we reported the applications of isolated acyl azoliums and expanded our methods to include both stoichiometric ester azoliums and three-component radical-relay reactions, which employed potassium trifluoroborates as radical precursors in the photoredox-mediated alkoxycarbonylation of trifluoroborates and synthesis of -aryloxy ketones. [33] However, under appropriate conditions radical-radical coupling is favored when (a) radicals are generated at equivalent rates, such as in photoredox-mediated reactions, and (b) the radicals exhibit different lifetimes, with one radical being persistent and the other transient. Potassium trifluoroborate, photoredox catalysis, acyl azolium compounds, radical-radical coupling, organophotocatalysis, ketones. [Extracted from the article] |
