Experimental and Theoretical Study of Ni(II)‐ and Pd(II)‐Promoted Double Geminal C(sp(3))−H Bond Activation Providing Facile Access to NHC Pincer Complexes: Isolated Intermediates and Mechanism

We report the first examples of metal‐promoted double geminal activation of C(sp(3))−H bonds of the N−CH(2)−N moiety in an imidazole‐type heterocycle, leading to nickel and palladium N‐heterocyclic carbene complexes under mild conditions. Reaction of the new electron‐rich diphosphine 1,3‐bis((di‐ter...
