unreactive C–H bonds, chemists have discovered reaction conditions that enable reactions of C(sp2)–H and C(sp3)–Hbonds with a variety of coupling partners. Despite these advances, the development of suitable ligands that enable catalytic C(sp3)–H bond functionalization remains a significant challenge. Herein we report the discovery of a mono-N-protected amino acid ligand that enables Pd(II)-catalysed

coordinated amine derivative enabled regioselective C–H functionalization remains challenging due to the elusive achievement of reactivity and selectivity simultaneously. Herein, regioselective C–Halkynylation of various readily transformable nitrogen functionalities was developed with great efficiency, with the assistance of the mono-N-protected amino acid (MPAA) ligand via Pd(II) catalysis proceeding via
