 In their subsequent works, Yu and co-workers report the application of the same strategy in "meta"-selective C-H cross-coupling, "meta"-C-H acetoxylation and "meta"-C–H olefination in a broad substrate scope.It is demonstrated that the "end-on" template not only work with the Pd(0)/Pd(II) catalytic cycle but is also compatible with the Pd(II)/Pd(IV) cycle.In all three works, addition of mono-"N"-protected amino acid (MPAA) such as "N"-acetyl glycine improves the reaction yields and enhances the regioselectivity.
