Role of Mono-N-protected Amino Acid Ligands in Palladium(II)-Catalyzed Dehydrogenative Heck Reactions of Electron-Deficient (Hetero)arenes: Experimental and Computational Studies
We report here that mono-N-protected amino acids (MPAAs), an important environmentally compatible structural motif, enable acceleration of Pd(II)-catalyzed dehydrogenative Heckreactions between pyridines and electron-deficient arenes with simple alkenes, leading to diversely functionalized C3- or meta-selective alkenylated pyridines and benzenes via non-chelate-assisted C–H activation.
