unactivated nucleophilic arenes are incorporated to give carboamination products in good yields. A variety of protected amide and carbamate groups are tolerated, and various five-, six-, and seven-membered rings are formed in good yields. Under these conditions, halobenzenes are activated at the C-H bond rather than the C-X bond, and very high regioselectivity for the para substitution product is observed

this study, a set of equilibrating alkyl–palladium complexes were subtly tuned to form either a primary or trisubstituted alkyl complex as the more thermodynamically favored state, depending on either the substrate or reaction conditions. An X‐ray crystal structure of the trisubstituted alkyl–palladium complex is presented and compared with the corresponding primary alkyl complex. The mechanism for
