Abstract2,4,6-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.Graphical Abstract
The preparation of .alpha.-carbonylphosphine oxides by oxidizing an .alpha.-hydroxyalkyl phosphine oxide with an organic hydroperoxide or of an organic peroxy acid in the presence of a compound of a Group IV to Group VIII metal in the periodic table, and novel .alpha.-hydroxybenzyl phosphine oxides. .alpha.-Carbonylphosphine oxides are used as photoinitiators for polymerizable compositions.
