Industrially important triaryl phosphites, traditionally prepared from PCl3, have been synthesized by a diphenyl diselenide-catalyzed one-step procedure involving white phosphorus and phenols, which provides a halogen- and transition metal-free way to these compounds. Subsequent oxidation of triaryl phosphites produces triaryl phosphates and triaryl thiophosphates. Phosphorotrithioates are also prepared efficiently from aromatic thiols and aliphatic thiols.

Flow synthesis techniques have received a significant amount of attention due to their high productivity. However, when reaction condition is heterogeneous, it is usually difficult to adapt it to flow synthesis. Herein, by selecting appropriate reagents, the synthesis of phosphate esters, which is commonly heterogeneous, was made homogeneous, enabling synthesis in flow systems. In addition, reaction rate was accelerated compared to the batch system. It was demonstrated that not only can the high productivity of flow synthesis be achieved in flow, but also high productivity can be achieved by accelerating the reaction. Finally, we demonstrated the synthesis of the Akiyama-Terada catalyst, a chiral organocatalysts, in a short period.
