Diphenyl Diselenide-Catalyzed Synthesis of Triaryl Phosphites and Triaryl Phosphates from White Phosphorus

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.

Nickel-catalyzed amination of aryl phosphates through cleaving aryl C-O bonds

The amination of triaryl phosphates was achieved using a Ni(II)-(σ-Aryl) complex/NHC catalyst system in dioxane at 110 °C in the presence of NaH as base. Electron-neutral, -rich, and -deficient triaryl phosphates were coupled with a wider range of amine partners including cyclic and acyclic secondary amines, aliphatic primary amines, and anilines in good to excellent yields.

Evaluation of kinetic parameters from the synthesis of triaryl phosphates using reaction calorimetry

Triaryl phosphates were prepared by a "one-pot" methodology through the reaction of sodium phenoxides with phosphorus oxychloride. This system can be described as a semi-batch reaction, where the phenoxides were synthesized inside the reactor anda solution of phosphorus oxychloride in toluene was added continuously through a pump. These highly exothermic reactions were performed in a Mettler RC-1 reaction calorimeter. The aim of this work was to evaluate the reaction rate and the reaction rate constant through the study of the rate of heat release. Although the phenoxides react almost immediately with phosphorus oxychloride, it was possible to notice the slight differences among the sodium phenoxides studied. The phenoxide bearing an electron-donating group (methoxy) was the most reactive, and the one bearing an electron-withdrawing group (nitro) was the least reactive one. The reactions could be considered to be feed-controlled. It was demonstrated that the reaction temperature does not affect the reaction rate and reaction rate constant in the same way that the feed rate of the phosphorus oxychloride does.
