摘要
Treatment of primary alkyl triflates or iodides with the potassium salt of diethyl (alpha -fluoro-alpha -phenylsulfonyl methyl)phosphonate yields (alpha -fluoro-alpha -phenylsulfonylalkyl)phosphonate These can be cleanly desulfonated, in a matter of minutes, with Na(HS) in MeOH/THF/NaH2PO4. This two-step procedure complements previously reported triflate displacement approaches to alpha -nonfluorinated and alpha,alpha -difluorinated phosphonates.
