Selective Reduction of Nitro Compounds With Titanium(II) Reagents

The reduction of nitro compounds to amines, an important syntheticre action, is us ually accomplished by means of catalytic hydrogenation,¹ metal and acids, reduction with hydridereayents and sulfurated sodium borohydride.⁶ A feu, attemptsat the reduction of ni tro group susing transition metal chloridesin the presence of sodium borohydride have also been reported.⁷
