this report constitutes the first biaryl synthesis enlisting common primary amides by N–C bond activation. This report also discloses for the first time the potential of generic, acyclic secondary amides as arylating reagents in directed C–H arylation. Considering the fundamental importance of biaryls and the key role of primary amides in organic synthesis, we expect that this concept by synergistic
通过高化学选择性的CH / C-N / CC裂解,非酸性C(sp 2)-H键与伯酰胺作为芳基化剂的直接C-H芳基化反应首次实现。到成功的关键是铑的协同组合(I)催化和路易斯碱催化,它可以促进的惰性选择性后通用伯酰胺的C-N键的激活ñ -叔-丁氧基羰基的活化非常有效。值得注意的是,该报告构成了第一个联芳基化合物的合成,该联芳基化合物通过N-C键活化激活了常见的伯酰胺。该报告还首次公开了在环戊基化芳基化反应中,通用的无环仲酰胺作为芳基化剂的潜力。考虑到联芳基的基本重要性和伯酰胺在有机合成中的关键作用,我们期望通过协同催化芳基-芳基偶联的概念,将开辟广泛的催化应用领域。
