Efficient interconversion of α,α-difluoromethylenephosphonates and α,α-difluoromethylenephosphonothioates

Treatment of dialkyl 1,1-difluoromethylenephosphonates 1 with Lawesson's reagent cleanly produces the corresponding dialkyl 1,1-difluoromethylenephosphonothioates 2. The reaction can be extended to dialkyl 1,1-difluoromethylenephosphinates and to dialkyl 1,1-difluoromethylenephosphine oxides. The reversed transformation (i.e. converting dialkyl 1,1-difluoromethylenephosphodioxirane 7 or perfluoro-cis-2-n-butyl-3-n-propyloxaziridine 8, and produces the desired phosphonates in high yield. The synthetic interest of these transformations is discussed.

Oxidation of alcohols by perfluoro-cis-2,3-dialkyl oxaziridines

Perfluoro-cis-2,3-dialkyloxaziridines oxidize secondary alcohols 2 to the corresponding ketones 4 at room temperature. The reaction has been carried out with uniformly high yields on simple acyclic alcohols as well as more complex substrates such as α-hydroxy esters, borneols, and sterols.
