WebbWith respect to the mechanism, the photoelectrochemical redox catalyst [Mes-Acr +]ClO 4 − 1 is initially irradiated (with blue LEDs) to its highly oxidizing excited state 2 (E red = 2.06 V vs. SCE in MeCN). This undergoes a single-electron transfer (SET) with the organotrifluoroborate leading to the acridinyl radical 3 and an alkyl radical.
