selective N-alkylation of amines with alcohols, that is in situ generated from Ni(COD)2 and KOH under ligand-free conditions. This novel method is very efficient for the functionalization of aniline and derivatives with a wide range of aromatic and aliphatic alcohols as well as diols and exhibits excellent functionalgroup tolerance including halides, benzodioxane and heteroaromatic groups. Several TEM measurements

selective methods, but the re- action conditions are somewhat harsh, as strong reducing reagents must be used. Nowadays, the formation of C-N bonds via cross- coupling reactions is an essential methodology for the preparation of nitrogen-containing compounds. Recently, different transition-metal-promoted reactions have been developed for the synthesis of secondary amines: catalytic systems for N-alkylation
介绍了一种简单的铜促进的苯胺 N-单烷基化,它利用烷基硼酸作为烷基化伙伴。该反应在回流的二恶烷中进行,它允许在一个步骤中对许多结构和电子不同的苯胺进行官能化。进行了广泛的研究以证明这种新方法在制备苯乙基苯胺方面的实用性。芳香胺是生物活性化合物,广泛存在于制药和农业化学工业中。1 因此,开发新的合成方法仍然是一个活跃的研究领域。特别吸引人的是广泛使用的初级苯胺转化为相应的次级苯胺。直接烷基化通常通过在碱存在下与烷基卤或类似试剂反应来完成。这似乎是一个简单的转化,但在许多情况下,由于过度烷基化,伯苯胺的有效 N-单烷基化是不可能的,这会提供叔苯胺或季铵盐作为副产物。其他制备单烷基化苯胺的方法基于使用允许引入单个烷基的临时保护基团(例如氨基甲酸酯、苄基),然后去除保护基团(引入两个额外的步骤)过程)。然而,由于它们的毒性,必须避免使用许多烷化剂,尤其是在 API 和活性化合物合成的最后一步。羰基
