Sulfinamides are a versatile class of compounds that find applications in both organic synthesis and pharmaceuticals. Here we developed an efficient photocatalytic approach for the convenient preparation of sulfinamides. Commercially available potassiumtrifluoro(organo)borates and readily available sulfinyl amines are rationally used and converted to a series of alkyl or aryl sulfinamides in moderate to high

Lithiations ofN-phenylbenzenesulfinamides followed by
treatment with Michler’s ketone and subsequent cyclizations during
acidic workup provide 3,3-diaryl-3H-2,1-benzoxathiole 1-oxides in
reasonable to good yields. The title compounds 11a, c–e, h
develop dark-blue colours in acidic media.
