Tellurocarboxylic Acid Anhydride

Only a few representatives of tellurocarboxylic acid anhydrides have been prepared from tellurium, sodium telluride, or bis[trimethylsilyl] tellurium and alkanoyl or arenoyl chlorides. Diacyl telluriums are stable at 20°, however, they are very sensitive to air and moisture. [Pg.506]

A large number of stable /e-organo tellurocarboxylates were prepared from tellurolates and aliphatic1,2 or aromatic2 carboxylic acid chlorides or aliphatic carboxylic acid anhydrides . The tellurolates were obtained by reduction of diorgano ditelluriums with sodium borohydride. [Pg.501]

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]
