Polyfluoroalkyl N-(trifluoromethylsulfonyl)amidosulfites, number one stable NH-containing amidosulfites

Abstract
We prepared for the first time NH-containing amidosulfites, polyfluoroalkyl N-(trifluoro-methylsulfonyl) amidosulfites CF3SO2NHS(O)ORF, by reaction of N-sulfinyl-trifluoromethanesulfonamide CF3SO2N=S=O with alcohols RFOH. Amidosulfites were formed also in reaction of chlorosulfites RFOS(O)Cl with trifluoromethanesulfonamide, with its sodium salt, and N-trimethylsilyl derivative.
