Abstract

Thiation of N, N-biphthalimide in a search for new axially chiral ligands gave a mixture of oligothiobiphthalimides; X-ray crystallography shows that the achiral isomer of dithiodioxobiphthalimide, 1,3-dithioxo-1H-3H-[2,2′]biisoindolyl-1′,3′-dione is formed, which may imply a change in the mechanism of thiation between mono- and di-phthalimides.
