ortho-Acetoxylation of Phosphonic and Phosphoric Monoacids via Pd(II) Catalysis
摘要:
A simple and efficient method is developed for Pd-catalyzed ortho-acetoxylation using organophosphates, namely, benzylic phosphonic and aryl phosphoric monoacids, as the directing group.
Palladium(II)-Catalyzed Ortho-Arylation of Benzylic Phosphonic Monoesters Using Potassium Aryltrifluoroborates
摘要:
The new monophosphonic acid directing group was successfully utilized in the Pd (II)-catalyzed orthoarylation of benzylic phosphonic monoesters using potassium aryltrifluoroborates. A wide range of benzylic phosphonic monoesters underwent clean ortho-arylation in high yields, and excellent functional group tolerance was also observed.
