Oxidation of 1,2,5-Thiadiazolidine 1,1-Dioxides: Synthesis of Diaryl 1,2-Diketones
Treatment of 3,4-diaryl 1,2,5-thiadiazolidine 1,1-dioxides with selenium dioxide followed by hydrolysis of the crude oxidation product furnishes the corresponding diaryl 1,2-diketones. Symmetrical and unsymmetrical diketones are readily prepared by this method.

Intramolecular imine cross-coupling in dibenzylidine sulfamides: Synthesis of unsymmetrical 1,2-diaryl ethanediamines
Intramolecular reductive cross-coupling of unsymmetrical dibenzylidene sulfamides generates the corresponding cyclic sulfamides in good yield. These intermediates are readily converted to the free, unsymmetrical 1,2-diaryl ethanediamines.
