REDUCTION OF AROMATIC NITRO COMPOUNDS WITH SODIUM TELLURIDE

Suzuki, Hitomi,Manabe, Hajime,Inouye, Masahiko

, p. 1671 - 1674 (1985)

Sodium telluride, prepared by heating tellurium with Rongalite in aqueous sodium hydroxide, easily reduces aromatic nitro compounds to the corresponding amines in good yields.The reduction can be carried out using a catalytic amount of tellurium, since sodium telluride is readily regenerated in the presence of excess Rongalite.
