A Novel Synthesis of Organic Tellurium Compounds by the Use of Electrochemically Generated Polytelluride-ions
The cathodic polarisation of a tellurium electrode in aprotic solutions gives rise to polytelluride anions, which react with alkylhalides to the corresponding disubstituted ditellurides. By this method of electrosynthesis a number of organic ditellurides can be simply prepared and without danger. Dialkylditellurides of the general formula R-Te-Te-R (2a–r) can be produced with high yields. The reaction with α,ω-dihalides gives heterocycles, which involve one or two tellurium atoms in the ring (5a–d, 6–8). The electrochemical reduction of tellurium in the presence of methyliodid yields trimethyltelluroniumiodid (9).
