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

Pd-catalyzed highly para-selective C-H arylation of monosubstituted arenes (including toluene) is developed for the first time using an F+ reagent as a bystanding oxidant. This finding provides a new retrosynthetic disconnection for para-substituted biaryl synthesis via C-H/C-H cross-coupling.
