Light-induced perfluoroalkylative carbonylation of unactivated alkenes with a recyclable photocatalyst

The development of heterogeneous catalysis difunctionalization of olefins is of great significance because it can save costs in the industry. Here, we report the perfluoroalkyl carbonylation reaction of inactive olefins catalyzed by titanium dioxide under light, obtaining β -perfluoroalkylamide compounds. The catalyst has high activity and wide functional group tolerance and can maintain high activity after multiple cycles. This catalyst reduces the use of precious metals, avoids ligands, and can easily be separated from the reaction mixtures.
