protocol for the Pd(II)-catalyzed C-H alkenylation reaction of substituted N-allylanilines via an unusual 6-endo process has been developed. A density functional theory (DFT) study of the mechanistic pathway has shown that the coordination of the remote protecting group to the palladium center is determinant for the control of the regioselectivity in favor of the 6-endo process. The reaction would proceed
