Tellurinyl Chloride

Ethoxyphenyl Tellurium Trichloride3 To a vigorously boiling suspension of 9.0 g (30 mmol) 4-ethoxybeiizcne tellurinyl chloride in 50 ml anhydrous carbon tetrachloride is added a solution of 6.4 g (60 mmol) butyryl chloride in 5 ml carbon tetrachloride. The refluxing mixture is stirred for 1 h. On cooling, 4-ethoxypheny] tellurium trichloride precipitates. The precipitate is collected by filtration and recrystallized from acetic acid. The filtrate is stripped of the solvent and the residue distilled at atmospheric pressure. Butyric anhydride boiled at 198° yield 89%. 

Aryl tellurinyl chlorides and carboxylic acid chlorides in refluxing carbon tetrachloride produced aryl tellurium trichlorides and carboxylic acid anhydrides6.
