To Organo Tellurium Halides

2-Nitrophenyl tellurium tribromide and 2-benzeneazophenyl tellurium trichloride were reduced to the aryl tellurium halide by sodium hydrogen sulfite , disodium disulfite, or hydrazine hydrate . 

An exeess of reducing agent yielded the diaryl ditellurium compounds  

3-Diphenyl-3-oxo-l-propen-l-yl tellurium tribromide was reduced by hypophosphorous acid to the corresponding tellurium bromide . These oxopropenyl tellurium trihalides lose halogen on slight heating and are converted to the tellurium monohalides.  

Aryl tellurium trichlorides treated with the thiosemicarbazides ofbenzaldehydes or methyl phenyl ketones produced the thiosemicarbazone complexes of the aryl tellurium monochlorides .
