Diaryl tellurides 5 are prepared by two synthetic routes: a) a one-pot procedure using elemental tellurium (1), diethyl phosphite (2) and sodium hydride in ethanol, followed by treatment with arenediazonium fluoroborates 4; b) treatment of sodium telluride (6) with arenediazonium fluoroborates 4 in dimethylformamide. In both cases, good yields are obtained.
