SN - 00221139 KW - Trimethylsilyl esters KW - Phosphorochloridofluoridate KW - Phosphorobromidofluoridate KW - Diphosphorodifluoridate KW - Condensation reations KW - Thermal decomposition N2 - Trimethylsilyl phosphorochloridofluoridate, Me3SiOP(O)FCl, has been prepared by reaction of POFCl2 with hexamethyldisiloxane or by treatment of bis(trimethylsilyl) phosphorofluoridate with phosphorus pentachloride. The compound could be purified by vacuum distillation and has been isolated in 55% yield. The ester Me3SiOP(O)FBr is formed in an analogous reaction of POFBr2 with (Me3Si)2O, however, its susceptibility to spontaneous decomposition makes its isolation unfeasible. Condensation of Me3SiOP(O)FCl with (Me3SiO)2P(O)F or heating of POFBr2 with excess hexamethyldisiloxane gave bis(trimethylsilyl) diphosphorodifluoridate,(Me3SiO)2P2O3F2,in 45 to 53% yield. The existence of both expected diastereoisomers was revealed by 19 F and 31 P NMR spectroscopy. ER -
