Cobalt-Catalyzed Direct Arylation and Benzylation by C[BOND]H/C[BOND]O Cleavage with Sulfamates, Carbamates, and Phosphates


  • Support by the DFG, the Georg-August-Universität Göttingen, and the Chinese Scholarship Council (fellowship to W.S.) is gratefully acknowledged. We thank Ayesha Babar for the synthesis of starting materials, as well as Dr. Benudhar Punji for helpful discussions and preliminary experiments with aryl chlorides.

Preiswerte Cobalt-Katalysatoren ermöglichen die erste direkte Arylierung und Benzylierung von (Hetero)arenen mit einer Vielzahl von Arylcarbamaten, -sulfamaten und -phosphaten. Die nichtradikalische C-H/C-O-Arylierung gelang sogar bei Umgebungstemperatur.
