干燥的 THF中加入 1当量 Zr Cl4,再在 0℃下加入 4当量Na BH4和 1当量脂族或芳族硝基化合物的 THF溶液 ,室温反应或回流数小时即得相应的伯胺。 1 0例收率 78%～ 92 %。ZrCl_4-NaBH_4系统还原硝基成伯胺@张贞发@Chary KP One equivalent of ZrCl4 was added to the dry THF and then four equivalents of Na BH4 and one equivalent of a solution of the aliphatic or aromatic nitro compound in THF were added at 0 ° C and the corresponding primary amine was obtained by reaction or reflux at room temperature for several hours. 10 cases of the yield of 78% to 92%.
