examples of catalysis using nickel complexes have been reported. In this work, the Ni-catalyzed transformation of ortho C-H bonds utilizing chelation assistance, such as oxidative cycloaddition of aromatic amides with alkynes, has been achieved.
尽管使用镍络合物(Kleiman, JP; Dubeck, MJ Am. Chem. Soc. 1963, 85, 1544)实现了涉及裂解CH键的邻位金属化的开创性例子,但尚未报道使用镍络合物进行催化的例子。在这项工作中,利用螯合辅助,如芳族酰胺与炔烃的氧化环加成,实现了 Ni 催化的邻位 CH 键的转化。
