Halides to Trihalides

Via Reactions Affecting the Anions 10.1.1. Conversion of Halides to Trihalides 

Appropriate triphenyl telluronium halides dissolved in chloroform were treated with a slight excess of bromine or iodine. Addition of diethyl ether to the reaction mixture precipitated triphenyl telluronium trihalides.  

Trimethyl telluronium iodide and iodine combined to give purple trimethyl telluronium triiodide (m.p. 76°, from ethyl acetate).
