The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this

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.

Patented procedures are also available in the literaturei ‘’ for the synthesis of triarylphosphates. Some of the reported methods have limitations such as (i) drastic reaction conditions,? (ii) liberation of hydrogen chloride which may cause corrosion problems in industrial reactors, (iii) tedious work-up, and (iv) long reaction times. In certain cases, pyridine or dialkylanilines have been used to neutralize

the synthesis of an ionic-liquid (IL)-supported organotelluride catalyst and its application as a recyclable catalyst for the aerobic oxidation of phosphite esters to phosphate esters. This method shows high conversion rates, allows the ready isolation and purification of the resulting products, and exhibits good reusability of the catalyst.
