Through Reactions with Organic Tellurium Compounds

Through Reactions with Organic Tellurium Compounds [Pg.334]

Aryl tellurium trihalides and equimolar amounts of diaryl ditellurium compounds in refluxing dichloromethane produce diaryl tellurium dihalides and elemental tellurium [Pg.334]

Aryl tellurium halides, the postulated intermediates, are polymeric substances in which the tellurium atoms are connected by halogen bridges. The polymer network facilitates the migration of aryl groups required by this reaction . [Pg.334]

Aryl tellurium trichlorides in boiling benzene are said to be in equilibrium with diaryl tellurium dichloride and tellurium tetrachloride. Removal of the tellurium tetrachloride by copper forces the reaction toward completion. [Pg.334]

Refluxing 2-chloro-2-phenylethenyl tellurium trichloride in acetic acid is reported to produce bis[2-chloro-2-phenylethenyl] tellurium and bis[2-chloro-2-phenylethenyl] tellurium dichloride. [Pg.334]
