s were synthesized by the palladium‐catalyzed, oxidative‐addition‐initiated activation and arylation of inert C(sp3)H bonds. Pd(OAc)2 and P(o‐tol)3 were used as the catalyst and ligand, respectively, to improve the efficiency of the reaction. A further advantage of this reaction is that it could be performed in air. A relatively rare seven‐membered palladacycle was proposed as a key intermediate of
3,4-二氢喹啉酮是通过钯催化,氧化加成引发的惰性C(sp 3)H键的芳构化而合成的。Pd(OAc)2和P(o- tol)3分别用作催化剂和配体,以提高反应效率。该反应的另一个优点是它可以在空气中进行。有人提出了一种相对罕见的七元帕拉达环作为催化循环的关键中间体。
