In this study, we introduce an efficient and streamlined metallophotoredox approach for decarboxylative oxygenation via visible-light-induced ligand-to-metal charge transfer (LMCT). Our method simplifies the transformation of aryl aliphatic carboxylic acids into their corresponding aryl aldehydes and ketones, utilizing iron(III) triflate as a photo catalyst in the presence of TMEDA as a ligand. This strategy not only enhances environmental sustainability but also expands the potential for late-stage functionalization of complex molecules and bioactive compounds.
