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

Abstract: 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 exhi

Process for preparation of phosphorane and phosphonyl compounds

The invention relates to the field of new materials of fine chemicals, in particular to a new safe, convenient, mild, efficient, environment-friendly and economical preparation process technology of phosphorane and phosphonyl compounds.

Palladium-catalyzed C–P bond activation of aroyl phosphine oxides without the adjacent “anchoring atom”

A novel palladium-catalyzed decarbonylation of aroyl phosphine oxides to prepare phosphine oxides from carboxylic acids is developed. Without the adjacent “anchoring atom”, the challenging C–P bond activation is achieved in high selectivity. The disclosure of this reaction provides a new example of C–P bond activation and helps to extend the understanding of the property of C–P bond.
