Herein we report a highly para-selective C–H olefination of aniline derivatives by a Pd/S,O-ligand-based catalyst. The reaction proceeds under mild reaction conditions with high efficiency and broad substrate scope, including mono-, di-, and trisubstituted tertiary, secondary, and primary anilines. The S,O-ligand is responsible for the dramatic improvements in substrate scope and the high para-selectivity
在此,我们报道了通过 Pd/S,O-配体基催化剂对苯胺衍生物进行高度对位选择性 C-H 烯化。该反应在温和的反应条件下进行,反应效率高,底物范围广,包括单、二和三取代的叔、仲和伯苯胺。S,O-配体导致底物范围的显着改善和观察到的高对位选择性。该方法操作简单、可扩展,并且可以在有氧条件下进行。
