摘要
Abstract An efficient method has been reported for the chemoselective reduction of aryl diazonium tetrafluoroborates to corresponding hydrazines or anilines with nickel boride generated in situ from nickel chloride and sodium borohydride at room temperature using 1:1:3 or 1:2:6 molar ratio of substrate : NiCl 2 : NaBH 4 . The aryl amines are obtained by in situ reduction of aryl hydrazines formed initially. Halo, carboxy, carboethoxy and methoxy groups remain unaffected under these conditions. Mild reaction conditions, easy work‐up and chemoselectivity are major advantages of this new procedure.
