Some aryltellurium(IV) compounds react with iodine and bromine to give the corresponding aryl halides in good to moderate yields (iodo- and bromodetelluration).The addition of ammonium, cesium or potassium fluoride, antimony(V) chloride, and mercury(II) chloride accelerates the reaction in some cases.Compared to these halogenodetellurations, chlorodetelluration and cyanodetelluration of these compounds were very sluggish when various chlorinating agents and metal cyanides were used under several reaction conditions.
