Reactions that enable carbon–nitrogen, carbon–oxygen, and carbon–carbon bond formation lie at the heart of synthetic chemistry. However, substrate prefunctionalization is often needed to effect such transformations without forcing reaction conditions. Development of direct coupling methods of abundant feedstock chemicals is therefore highly desirable for the rapid construction of complex molecular scaffolds. We report herein a copper-mediated, net-oxidative decarboxylative coupling of carboxylic acids with diverse nucleophiles under visible light irradiation. Preliminary mechanistic studies suggest that the relevant chromophore in this reaction is a Cu(II) carboxylate species assembled in situ. We propose that visible light excitation to a ligand-to-metal charge transfer (LMCT) state results in a radical decarboxylation process that initiates the oxidative cross-coupling. The reaction is applicable to a wide variety of coupling partners, including complex drug molecules, suggesting that this strategy for cross-nucleophile coupling would facilitate rapid compound library synthesis for the discovery of new pharmaceutical agents.
