Benzyl Protection of Phenols under Neutral Conditions: Palladium-Catalyzed Benzylations of Phenols
Benzyl protection of phenols under neutral conditions was achieved by using a Pd(η3-C3H5)Cp–DPEphos catalyst. The palladium catalyst efficiently converted aryl benzyl carbonates into benzyl-protected phenols through the decarboxylative etherification. Alternatively, the nucleophilic substitution of...

Abstract | Benzyl protection of phenols under neutral conditions was achieved by using a Pd(η3-C3H5)Cp–DPEphos catalyst. The palladium catalyst efficiently converted aryl benzyl carbonates into benzyl-protected phenols through the decarboxylative etherification. Alternatively, the nucleophilic substitution of benzyl methyl carbonates with phenols proceeded in the presence of the catalyst, yielding aryl benzyl ethers. |
