Pd(OAc)(2)-catalyzed synthesis of benzyl phenyl ether derivatives with H2O2 as an oxidant in neat water

摘要

A new protocol for Pd(OAc)(2)-catalyzed reactions of different benzyl bromides and various arylboronic acids has been developed to form functionalized benzyl phenyl ethers. This method represents the first instance where arylboronic acid is used as a reaction substrate for benzyl phenyl ether synthesis with H2O2 as the green oxidant under atmospheric oxygen and pure H2O2 as an environmental friendly solvent without the requirement for phosphine- and N-based ligands, remarkable functional group tolerance, and considerable yield.
