Direct cyanations of arenes and heteroarenes bearing only weakly coordinating amides were accomplished using a robust ruthenium(II) catalyst. The user-friendly C(sp2)âH activation occurred with the assistance of carboxylate with high site-selectivity, excellent functional group tolerance and ample scope.
直接利用一种稳定的
钌(II)催化剂,实现了仅含弱配位酰胺的
芳烃和杂
芳烃的直接
氰化反应。在
羧酸盐的帮助下,实现了用户友好型的C(sp2)–H活化,具有高定位选择性、优异的官能团兼容性和广泛的应用范围。
