3,3-Diaryl-3H-2,1-benzoxathiole 1-oxides: new sultine colour-formers for carbonless imaging

Abstract

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.
