Abstract

The biaryl motif is found in a range of pharmaceuticals, natural products, agrochemicals, ligands, conducting polymers, liquid crystals and advanced materials. 1 The Negishi cross-coupling reaction utilizing organozinc reagents represents a powerful method for the synthesis of this privileged structural scaffold. 2 One major disadvantage of Pd or Ni-catalyzed Negishi couplings is the rather long reaction times involving hours or even days. Recent evidence suggests ...
