Transition-metal-catalyzed reductive coupling reactions have attracted considerable interest for several decades since the development of reductive polymerization of carbon monoxide by Fischer and Tropsch.[1] Hydroformylation [2] and the Nozaki–Hiyama–Kishi reaction [3] are other important examples, and in the past decade dozens of nickel-and rhodiumcatalyzed reductive coupling reactions have also been described.[4] Represented ...
