Unsymmetrical diaryltellurium dichlorides

Unsymmetrical diaryltellurium dichlorides (general procedure) The aryltellurium trichloride (20 mmol) and the aryhnercury chloride (20 mmol) are heated under reflux in dry dioxane (30 mL) for 1.5 h. The solution is cooled at 10°C and the HgCl2 dioxane precipitate so formed is fdtered off and washed with a small volume of cold dioxane. The dioxane solution is then ponred into 1% HCl (100 mL) with vigorous stirring. The formed oily product crystallizes by friction and is separated by filtration and then washed with cold EtOH.
