DBN hexafluorophosphate salts as convenient sulfonylating and phosphonylating agents

Air-stable N -sulfonyl and N -phosphonyl DBN hexafluorophosphate salts have been synthesised under mild conditions as sulfonylating and phosphonylating agents. These salts are highly efficient in the sulfonylation and phosphonylation of a range of N - and O -nucleophiles to generate sulfonamides, sulfonate esters, phosphoramidates and phosphonate esters in good yields.
