Reported herein is a palladium‐catalyzed, directed γ‐C(sp3)−H arylation of protected thiols. The key is to utilize Michael acceptors as a dual reagent to install a protecting/directing group on thiols by a thiol‐Michael click reaction, and remove it later under basic conditions. The C−H arylation proceeds with high functional‐group tolerance and the deprotected thiols can be further transformed into...
Herein, we report the palladium‐catalyzed direct arylation of unactivated aliphatic C−H bonds in free primary amines. This method takes advantage of an exo‐imine‐type directing group (DG) that can be generated and removed in situ. A range of unprotected aliphatic amines are suitable substrates, undergoing site‐selective arylation at the γ‐position. Methyl as well as cyclic and acyclic methylene groups...
