Oxidation of H-phosphonate, H-phosphonothioate, or H-phosphonodithioat
e monoesters with iodine in pyridine in the presence of trimethylsilyl
chloride, followed by addition of triethylamine trishydrofluoride (TA
F) furnished rapid and quantitative formation of the corresponding pho
sphorofluoridate, phosphorofluoridothioate, or phosphorofluoridodithio
ate monoesters. Copyright (C) 1996 Elsevier Science Ltd.
