Palladium on carbon (Pd/C)-catalyzed oxidative transformations of primary and secondary benzylic ethers in ethylene glycol as a solvent and reagent in an oxygen atmosphere produced the corresponding hydroxyethyl esters and cyclic ketals, respectively. Commercially-available and heterogeneous Pd/C was easily removed by filtration, and molecular oxygen was used as a clean oxidant.

钯对苯甲醚的碳催化氧化转化

在氧气中，钯在碳（Pd / C）上催化伯和仲苄基醚在乙二醇中作为溶剂和试剂的氧化转化分别产生了相应的羟乙基酯和环状缩酮。通过过滤可轻松除去市售的多相Pd / C ，并将分子氧用作清洁的氧化剂。
