Bis (p-hydroxyphenyl) ditelluride and bis (3-methyl-4-hydroxyphenyl) ditelluride have been synthesized by reduction of corresponding hydroxyaryl tellurium (IV) trichloride with hydrazine hydrate. These ditellurides have been investigated as catalytic reducing agents in presence of sodium borohydride and sodium hydroxide in ethanol. They reduce nitrobenzene to azoxybenzene and azobenzene, p-chloronitrobenzene to 4,4'-dichloroazobenzene and p-nitroanisole to 4,4'-dimenthoxyazobenzene. The catalytic reducing property is found to be more in case of bis (3-methyl-4-hydroxyphenyl) ditelluride as compared to bis (p-hydroxyphenyl) ditelluride.
