Amide-Ligand-Controlled Highly <i>para</i>-Selective Arylation of Monosubstituted Simple Arenes with Arylboronic Acids

Abstract

Pd-catalyzed highly para-selective arylations of monosubstituted simple arenes with arylboronic acids to widely existed biaryls have been developed. Inspired by requisite amide-directing groups in reported selective oxidative couplings, amide ligands, especially DMF, are designed and found to be critical for the selectivity control in current arylations.
