Halotellurates

Symmetrical divinyl tellurides VI have been prepared via a ylidation reaction involving the treatment of bis-phosphonium halotellurate I with excess base and then with aldehydes in THF at -1S°C (method c). °... [Pg.92]

When tetramethylenedichlorodiiodotellurates(IV) were refluxed in chloroform with two molar equivalents of potassium cyanate or thiocyanate, tetramethylenediiododipseudo-halotellurates(IV) were isolated in quantitative yield1. [Pg.671]

The halogen atoms in the halotellurate anions can be exchanged by treatment with hydrobromic acid, hydrochloric acid, or potassium iodide1. [Pg.695]

The reactions of alkali metal, ammonium, phosphonium, or arsonium halides with diorgano tellurium dihalides produce diorganotrihalotellurates or diorgano tetra-halotellurates (page 668). [Pg.574]
