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.

NOVEL COMPOUND AND RESIN COMPOSITION CONTAINING THE SAME

To provide a compound which can demonstrate flame retardancy equal to or higher than V-1 of the UL94 standard by adding a flame retardant to resin containing aromatic polyester and styrene polymer. To provide a compound represented by General Formula (1) of Claim 1. In General Formula (1), R1 to R3 are alkyl groups having 1 to 4 carbon atoms and R1 to R3 may be the same or different from each other.

"One-pot" Synthesis of Triaryl Phosphates a Reaction Calorimetry Approach

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
