Pd nanoparticles/polyoxometalate–ionic liquid composites on SiO2 as multifunctional catalysts for efficient production of ketones from diaryl ethers†
Abstract
The high stability of C–O bonds in diaryl ethers limits the valorization of lignin. Herein, reductive hydrolysis of C–O bonds in diaryl ethers was achieved over Pd nanoparticle/polyoxometalate–ionic liquid composite supported on SiO2 (Pd/H2[POM-IL]@SiO2) in water, selectively yielding ketones free from their alcohol counterparts in unprecedentedly high yields (>80%).
