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.

Triaryl phosphates were obtained in yields ranging from 85-96percent in a "one-pot" synthesis via an alkaline route: an ethanolic solution of sodium hydroxide was added to a solution of substituted phenol in toluene.The mixture was distilled until all ethanol was removed.Phosphorus oxychloride was then added and the toluene was distilled.The triaryl phosphates were characterized by NMR (1H and 31P), MS and FTIR.The heat capacity (Cp), the total heat transfer coefficient (U) and the reaction enthalpy (ΔH) were determined for the synthesis of tris(4-chloro-3-methylphenyl), tris(p-cresyl), tris(o-methoxyphenyl) and tris(p-nitrophenyl) phosphates. - Keywords: Phosphate; NMR spectra; heat capacity; phosphorus oxychloride
