Formation and reaction behaviour of aryl-tellurium(II)-halogenides
Description
Aryl-tellurium(II)-haloganides, according to the author's results, can be quite generally prepared by the reaction of equimolar amounts of diaryl-ditellurides and halogen. By using non-polar solvent in which the reaction products are insoluble, the further reaction to aryl-tellurium(IV)-halogenides can be avoided. Aryl-tellurium(II)-halogenides, which so far have been prepared from diaryl-ditellurides and halogen, were subjected to the same reaction conditions as for the conversions of diaryl-ditellurides with aryl-tellurium(IV)-halogenides. Isotope labelling tests clearly showed the intermediary occurence of aryl-tellurium(II)-halogenides in these conversions. The isotope sup(123m)Te was used. (HK/LH)

Aryltellur(II)halogenide lassen sich nach den Ergebnissen des Authors ganz allgemein durch Umsetzung aequimolarer Mengen von Diarylditelluriden und Halogen darstellen. Durch Verwendung unpolarer Loesungsmittel, in denen die Reaktionsprodukte unloeslich sind, laesst sich die Weiterreaktion zu Arylteller(II)halogeniden vermeiden.-Arylteller(II)halogenide, die zuvor aus Diarylditelluriden und Halogen dargestellt worden waren, wurden den gleichen Reaktionsbedingungen unterworfen, wie sie bei den Umsetzungen der Diarylditelluride mit den Aryltellur(IV)halogeniden vorlagen. Isotopenmarkierungsversuche erbrachten den sicheren Beweis fuer das intermediaere Auftreten von Aryltellur(II)halogeniden bei diesen Umsetzungen, es wurde das Isotop sup(123m)Te verwendet. (HK)
