C–O and C–H bonds is reported. The reaction conditions are simple, and only transition-metal catalysts and ligands are essential. Mechanistic studies indicated that Ni catalyst played an important role in activating C–O bond, while the Cu one in activating C–H Bond. The developed system proved to be effective for cross-coupling of terminal alkynes with aryl carbamates.
据报道,多氟芳烃与氨基甲酸芳基酯通过sp 2 C-O和CH-H键的裂解而发生交叉偶联。反应条件简单,仅过渡金属催化剂和配体是必需的。机理研究表明,镍催化剂在活化C-O键中起重要作用,而铜在活化C-H键中起重要作用。事实证明,开发的系统对于末端炔烃与氨基甲酸芳基酯的交叉偶联是有效的。
