Here, we report a highly effective and chemoselective method of preparing substituted indoles from (E)-2-nitropyrrolidinostyrenes via hydrogenation in the presence of a rhodium catalyst doped by additives such as Ni(NO3)2·6H2O, Fe(OAc)2 or Co(acac)3. These hydrogenation conditions may also be applied to other substrates. Aromatic nitro compounds and olefins can be selectively reduced in the presence
这里,我们报告从(制备取代的吲哚的一个非常有效的和化学选择性方法ë)-2- nitropyrrolidinostyrenes通过氢化在铑催化剂掺杂的存在下,通过添加剂如Ni(NO 3)2 ·6H 2 O,Fe(上OAC )2或Co(acac)3。这些氢化条件也可以应用于其他基材。在芳族苄基醚,芳族卤化物和芳族醛的存在下,可以选择性地还原芳族硝基化合物和烯烃。
