Due to the importance of allylamines in organic synthesis, the synthesis of reagents as potent precursors of aminofluoroolefins is reported from functionalized benzothiazolylsulfones. The key intermediate, a fluorovinyl sulfone, was prepared and functionalized by addition of aliphatic, aromatic amines and amino acid alkyl esters through an aza-Michael addition reaction.

aminosulfinates enabled the preparation of β-fluoroalkylamines in a photocatalyzed addition reaction of the corresponding aminodifluoroalkyl radicals to electron-deficient, electron-rich alkenes and vinylaryls or unactivated alkenes.
