functionalization of a broad panel of aromatic and olefinic derivatives (37 examples, up to 87 % yield), a real advance as existing routes were restricted to the SCF3 and SCF2H residues. Post-functionalization reactions further illustrated the synthetic value of this fluorinated motif.
通过Pd催化的C−H键活化成功实现了前所未有的C(sp 2 )-SCF 2 CO 2 Et键的构建。这种强大的方案允许对广泛的芳香族和烯烃衍生物进行功能化(37 个示例,产率高达 87%),这是一个真正的进步,因为现有路线仅限于 SCF 3和 SCF 2 H 残基。后官能化反应进一步说明了该氟化基序的合成价值。
Pd‐Catalyzed Directed Thiocyanation Reaction by C−H Bond Activation
The Pd‐catalyzed directed thiocyanation reaction of arenes and heteroarenes by C−Hbondactivation was achieved. In the presence of an electrophilic SCN source, this original methodology offered an efficient tool to access a panel of functionalized thiocyanated compounds (21 examples, up to 78 % yield). Post‐functionalization reactions further demonstrated the synthetic utility of the approach by converting
