with weakly coordinating groups normally requires a transient directing group or presynthesized nitrogen-based strong coordinating ligands. Herein, we report Pd(II)-catalyzed C(sp3)–H arylation and alkenylation of Weinreb amides. A commercially available, inexpensive sulfonic acid was employed to enhance the coordination of the catalyst with weak-coordinating substrates by increasing the electrophilicity
通过与弱配位基团螯合对 C-H 键进行 Pd 催化修饰通常需要一个瞬态导向基团或预先合成的氮基强配位
配体。在此,我们报告了 Pd(II) 催化的 Weinreb 酰胺的C(sp 3 )-H 芳基化和烯基化。通过增加原位形成的
钯催化剂的亲电性,使用市售的廉价
磺酸来增强催化剂与弱配位底物的配位。
