So far, the direct C−H alkenylation of aromatic nitriles with alkynes has not been achieved. Herein, we discribe the first manganese‐catalyzed C−H alkenylation of aromatic N−H imidates to access mono‐alkenylated aromatic nitriles. The reaction is accelerated by the presence of a catalytic amount of sodium pivalate. This protocol is also highlighted by the simple catalytic system, good compatibility
到目前为止,还没有实现芳族腈与炔烃的直接CH H烯基化。在本文中,我们描述了芳族N-酰亚胺的锰催化的CH-H烯基化反应,从而获得了单烯基化的芳族腈。通过催化量的新戊酸钠的存在促进反应。简单的催化体系,良好的官能团相容性,出色的单/二烯基化选择性以及E / Z立体选择性也突出了该方案。
