Reduction of aromatic nitro compounds to amines with hydriodic acid was reinvestigated. Under a milder non-refluxing condition (at 90Β°C for 2-4 h), the reduction proceeded efficiently with excellent chemoselectivity without affecting other functional groups including nitrile, ester, halide, carbonyl
## Abstract Aromatic amines were prepared in good yields by a novel reduction of aromatic nitro compounds with tellurium metal in nearβcritical water at 275Β°C.
Sodium borohydride is well known as one of the most excellent reducing agents for ketones, acid halogenides and some kinds of esters (1). The reagent, however, has no ability to reduce nitriles, amides and nitro compounds to corresponding
