Application of Visible-to-UV Photon Upconversion to Photoredox Catalysis: The Activation of Aryl Bromides.

Michal Majek1, Uwe Faltermeier2, Bernhard Dick2, Raúl Pérez-Ruiz3, Axel Jacobi von Wangelin4.   

Abstract

The activation of aryl-Br bonds was achieved by sequential combination of a triplet-triplet annihilation process of the organic dyes, butane-2,3-dione and 2,5-diphenyloxazole, with a single-electron-transfer activation of aryl bromides. The photophysical and chemical steps were studied by time-resolved transient fluorescence and absorption spectroscopy with a pulsed laser, quenching experiments, and DFT calculations.
