From sodium telluride

Sodium telluride, prepared from tellurium and sodium formaldehydesulfoxylate in aqueous sodium hydroxide, reacted with the diazonium salt that was obtained from bis[2-aminophenyl] ketone to produce telluraxanthone in 2% yield.  [Pg.837]

By treating 1,2-dichloro- or 1,2-dibromoarenes with Na2Te (from NaH and Te) in DMF at reflux.  [Pg.319]

Despite the low yield, the method deserves some use since the non-reacted tellurium can be recovered. [Pg.319]

A member of the class has been prepared from TeCl4 and 3,4-dihthio-2,5-dichloro-thiophene.  [Pg.319]

This compound is formed as by-product in the described preparation of TTef (see Section 5.11)  [Pg.320]

A similar reaction has been performed with a cyclalkene tellurolate. [Pg.320]

When the alkylating agent is insoluble in liquid ammonia, as in the case of long-chain compounds, an organic solvent is added to the sodium telluride residue after evaporation of the ammonia. Some cyclic and steroidal tellurides have been prepared from sodium telluride in ethanol and the appropriate dihalides. ... [Pg.13]

The following cyclic tellurium compounds were prepared from sodium telluride in ethanolic solution and the appropriate organic dihalides ... [Pg.373]

The following compounds were similarly prepared from sodium telluride obtained by the Rongalite method ... [Pg.377]

Tellurabicyclo[3.3.l]nona-2,6-diene, prepared from sodium telluride and 1,5-dibromoocta-2,6-diene, lost tellurium when heated at 175° in toluene in a sealed tube giving bicyclo[5.1.0]octa-2,5-diene b... [Pg.481]

Te-Esters of tellurocarboxylic acids were prepared from tellurolates and carboxylic acid chlorides or anhydrides, and from sodium telluride and aroyl chlorides". The following types of 7e-organo tellurocarboxylates have thus far been synthesized ... [Pg.499]

Tellurophens.—A detailed description of the synthesis of tellurophen (701) from sodium telluride and butadiyne has been published. Its chemical properties are similar to those of thiophen and selenophen. It can be... [Pg.495]
