From Diaryl Telluriums

When diaryl telluriums were oxidized with tert.-butyl hypochlorite and the oxidation products reacted with sodium sulfonamides, diaryl tellurium sulfonimides were obtained in quantitative yield,  

Bis[4-methaxyphenyl] Tellurium 4-Methylbenzenesulfonimide 1.7 g (5 mmol) of bis[4-methoxyphenyl] tellurium are dissolved in 70 ml of anhydrous chloroform, the solution is cooled to — 20°, stirred, and a solution of 0.54 g (5 mmol) of tcrt.-butyl hypochlorite in 20 m/ of anhydrous chloroform is added over 0,5 h. 

Irgolic Organo Tellurium Compounds with 2 Te —C Bonds or 1 Te = C Bond 

97 g (5 mmol) of sodium 4-methylbenzenesulfonamide are then slowly added, the resultant mixture is stirred at — 20° for 2 h, and then allowed slowly to warm to 20°. The mixture is filtered, the filtrate is evaporated under vacuum, and the residue is recrystallized from benzene/hexane (3/1, v/v) yield 2.6 g (100%) m.p. 152°. 

Diaryl telluriums and aryl methyl telluriums reacted with anhydrous chloramine-B and chloramine-T in chloroform in the presence of 18-crown-6 as the phase transfer reagent.

Diaryl tellurium dicarboxylates were prepared in good yields from diaryl tellurium dichlorides and anion exchange resins such as Amberlite IR45 and Amberlite IR400 in their carboxylate form. The carboxylate resins were obtained by treating the resins in the OHe-form with carboxylic acids or the resins in the Cle-form with sodium carboxylates4.
