From Tellurolates and Carboxylic Acid Chlorides

A large number of stable 7e-organo tellurocarboxylates were prepared from tellurolates and aliphatic or aromatic carboxylic acid chlorides or aliphatic carboxylic acid anhydrides. The tellurolates were obtained by reduction of diorgano ditelluriums with sodium borohydride. 

When 4-methylbenzenetellurolate and l,4-bis-[chlorocarbonyl]benzene were combined, l,4-bis[4-methylphenyltellurocarbonyl benzene was obtained .
