Effective Catalyst for Oxidation Synthesis of 2,4,6-Trimethylbenzoyldipenylphosphine Oxide: V/MCM-41

2,4,6-Trimethylbenzoyldipenylphosphine oxide (TPO) is an important photoinitiator, nevertheless some drawbacks exist in its synthesis. So V/MCM-41 catalysts were designed. Compared with commonly used VO(acac)2, V/MCM-41 catalysts exhibited excellent TPO yield (92.5%), which makes the usage of inorganic vanadium possible and is benefit both in academic and in industry.
