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.

METHOD OF PREPARING BIPHENYL-4-YL DIPHENYL PHOSPHATE COMPOSITION

Provided is a method of preparing a biphenyl-4-yl diphenyl phosphate composition for use as a flame retardant or a plasticizer for resin, including mixing phosphoryl chloride (POCl3), 4-phenylphenol, and a catalyst, so that first dehydrochlorination occurs; and further adding phenol, so that second dehydrochlorination occurs.

Process for producing triaryl phosphate

A process for producing triaryl phosphate, comprising reacting at least one specific aromatic hydroxy compound with phosphorus pentachloride to form a chlorophosphorane compound and reacting water, an alcohol, an alcohol aqueous solution or an alkaline aqueous solution with the chlorophosphorane compound. The process permits the production of triaryl phosphate at high yields at a low temperature for a relatively short period of time, making the removal and treatment of a catalyst simply and obviating the use of the catalyst in some cases.

SYNTHESIS OF TRIARYL PHOSPHATES CATALYZED BY POLYETHYLENE GLYCOLS IN A TWO-PHASE SYSTEM: PHASE TRANSFER CATALYSIS

The synthesis of triaryl phosphates has been accomplished, at room temperature, in nearly quantitative yields in a two-phase system with poly(ethylene glycol) as a phase transfer catalyst.
