The C-alkylation of nitroalkanes under mild conditions has been a significant challenge in organic synthesis for more than a century. Herein we report a simple Cu(I) catalyst, generated in situ, that is highly effective for C-benzylation of nitroalkanes using abundant benzyl bromides and related heteroaromatic compounds. This process, which we believe proceeds via a thermal redox mechanism, allows
一个多世纪以来,在温和条件下硝基烷烃的 C-烷基化一直是有机合成中的重大挑战。在此,我们报告了一种原位生成的简单 Cu(I) 催化剂,该催化剂使用丰富的苄基溴和相关的杂芳族化合物对硝基烷烃的 C-苄基化非常有效。我们相信这个过程是通过热氧化还原机制进行的,可以在温和的反应条件下获得各种复杂的硝基烷烃,并且代表了开发用于硝基烷烃烷基化的通用催化系统的第一步。
