Trichlorotellurium Sulfonates

When equimolar amounts of tellurium tetrachloride and silver arenesulfonate in nitrometh-ane were magnetically stirred for 8 to 10 hours at 20°, light-grey trichlorotellurium sulfonates were obtained after vacuum distillation of the solvent from the filtered reaction mixture.  

The same products were obtained from tellurium tetrachloride and the sulfonic acid anhydrides or the sulfonic acids.  

The trichlorotellurium sulfonates are moisture-sensitive and foam in air. They decompose at 50°. The compounds are only soluble in polar organic solvents. The solutions are nonconducting. 

Trichlorotellurium sulfonates form coordination compounds with sulfonates, pyridine, thiocyanate and oxo groups as ligands.  

Tris[fluoroalkoxy] tellurium fluorides are thermally unstable, moisture-sensitive liquids.
