Rhodium or Ruthenium‐Catalyzed Oxidative CH/CH Cross‐Coupling: Direct Access to Extended π‐Conjugated Systems

Abstract

Doubling up: a chemo- and regioselective oxidative cross-coupling between various N-heteroarene-containing arenes and heteroarenes has been carried out by rhodium- or ruthenium-catalyzed twofold C-H activation, to deliver an array of highly functionalized π-conjugated systems.
