Pd(II)-Catalyzed Olefination of Electron-Deficient Arenes Using 2,6-Dialkylpyridine Ligands

Abstract

Pd(II)-catalyzed meta-olefination of highly electron-deficient arenes is achieved through the use of a rationally designed mutually repulsive ligand. The combination of directed and nondirected C-H functionalization of arenes provides a versatile route for the synthesis of highly sought after 1,2,4-trisubstituted arenes.
