Congrats to Ke Chen et al. for the latest publication in Nat. Commun. We have developed a dinickel-complex-catalyzed dimerization and hydrocarbofunctionalization of unsymmetrical internal alkynes with organoborons, providing a series of pentasubstituted 1,3-dienes with excellent regio- and stereoselectivities. Mechanistic studies suggest that each Ni site can promote distinct elementary steps of two alkynes to generate a di-vinyl di-Ni intermediate. Such a mode of “binuclear convergent catalysis” is fundamentally different from the traditional mono-metallic catalysis and may provide new understanding on binuclear synergistic effects at atomic and molecular level.
