Reactions of N‐sulfonyldiarylchalcogenimides with diaryl ditellurides

Reactions of N‐sulfonyldiarylchalcogenimides with diaryl ditellurides Unlike the N‐sulfonylsulfimide 1a, which does not react with diaryl ditellurides 2 even at 180°C, the selenimide 1b, and tellurimides 1c,d convert quantitatively compounds 2 to N,N‐bis‐(N′‐p‐tosylimidoarenetellurinyl)‐p‐tosylamides 4a,b in refluxing benzene.

Abstract

Unlike the N‐sulfonylsulfimide 1a, which does not react with diaryl ditellurides 2 even at 180°C, the selenimide 1b, and tellurimides 1c,d convert quantitatively compounds 2 to N,N‐bis‐(N′‐p‐tosylimidoarenetellurinyl)‐p‐tosylamides 4a,b in refluxing benzene. The reactivity of N‐sulfonylchalcogenimides 1 increases in the order S < Se < Te. Diaryl telluroxides 6 readily oxidize ditellurides 2 to arenetellurinic anhydrides 5. The mechanisms of these reactions are discussed.
