Trimethylsilyl esters of general formula RR′POSiMe3 react in a quantitative and fully chemoselective way with sulphuryl chloridefluoride to give phosphorofluoridates RR′P(O)F of high purity under extremely mild conditions.
Phosphoroazolides, including nucleoside derivatives, can be converted smoothly into the corresponding phosphorofluoridates by reaction with benzoyl flouride. From these compounds oligonucleotides containing → P-F instead of → P-OH can be prepared.
