1-R-2,4-Dinitrobenzenes are regioselectively reduced with sodium dithionite at near-neutral pH into the product having amino group ortho to the substituent R. Although the yields of products varied from moderate to good, the procedure does not involve the use of transition metals.
1-R-2,4-二硝基苯在接近中性的 pH 条件下被连二亚硫酸钠区域选择性还原成具有取代基 R邻位氨基的产物。虽然产物的产率从中等到良好不等,但该过程不涉及使用过渡金属。
