From Diaryl Tellurium Benzenesulfonimides and Phenols

Equimolar amounts of diphenyl tellurium benzenesulfonimides and 1,4-dihydroxybenzene in anhydrous chloroform at 20° for 30 min yielded, among other compounds, a pale-yellow substance that is insoluble in benzene and consists of a diphenyl tellurium group and the dianion of hydroquinone  

Bis[4-methylphenyl] tellurium benzenesulfonimides and hydroquinone did not produce this phenolate. 

From Diorgano Tellurium Dialkoxides and Alcohols or Phenols 

Diorgano tellurium dimethoxides react with phenols in methanoP or in toluene . The diorgano tellurium diphenoxides precipitated from the reaction mixtures or were isolated after removal of the solvent and methanol by destination. The dimethoxides need not be isolated and purified. 

Bis[4-methylphenyl] Tellurium Bis[2-(4 -methylbenzylidenamino)phenoxide] A solution of sodium methoxi-de in 30 w/absolute methanol, prepared by the addition of 0.95 g (40 mmol) sodium to methanol, is added to a stirred solution of 9.40 g (20 mmol) of bis [4-methylphenyl] tellurium dibromide in 50 m/ dry toluene. Methanol is distilled from the reaction mixture until the temperature of the vapors reach 110°, Sodium bromide is removed by filtration. The filtrate, containing his 4-methylphenyl] tellurium dimethoxide, is added to a stirred solution of 8.44 g (40 mmol) of 2-(4-methylbenzylidenamino)phenol in 50 ml dry toluene. Most of the toluene is distilled under vacuum from the reaction mixture. The concentrate ( 30 ml) is mixed with an equal volume of absolute diethyl ether. The mixture is cooled to — 5°. The crystals are collected by filtration and recrystallized from hexane m.p. 135°.
