What is Tellurium tetrachloride?
Chemical properties
off-white to light yellow powder
The Uses of Tellurium tetrachloride
Tellurium(IV) chloride is used in organic synthesis to prepare Cl-C-C-TeCl3derivatives by reacting with alkenes and aryl tellurium compounds by reacting with electron rich arenes. It is involved in the preparation of diaryl telluride from anisole.
Safety Profile
Mutation data reported. Experimental reproductive effects. Incompatible with ammonia. Irritant. When heated to decomposition it emits very toxic fumes of Cland Te. See also TELLURIUM COMPOUNDS.
