REACTION OF PENTAERYTHRITOL WITH DIETHYL PHOSPHOROCHLORIDATE PENTAERYTHRITOL BIS-, TRIS-, AND TETRAKIS(DIHYDROGEN PHOSPHATES)

Reaction of pentaerythritol 1 with 1, 2 or 3 equivalents of diethyl phosporochloridate 2 yielded pentaerythritol tris(diethyl phosphate) 5.Treatment of pentaerythritol with 4 or more equivalents of 2 gave pentaerythritol tetrakis(diethyl phosphate) 6.Transesterification of 5 and 6 with trimethylsilyl chloride and sodium iodide in acetonitrile followed by treatment with water gave pentaerythritol tris(dihydrogen phosphate) 7 and pentaerythritol tetrakis(dihydrogen phosphate) 8 respectively.Pentaerythritol bis(dihydrogen phosphate) 9 was prepared by the hydrolysis of 3,9-dichloro 2,4,8,10-tetraoxa-3,9-diphosphaspiroundecane 3,9-dioxide 10.The compounds 7,8 and 9 were isolated as anilinium salts and characterized by 1H, 31P NMR spectra.
