Carbene Formation and Transfer at a Dinickel Active Site.

ABSTRACT: The synthesis and reactivity of a dinickel bridging carbene is described. The previously reported [ ^i-PrNDI]Ni₂(C₆H₆) complex (NDI = naphthyridine-diimine) reacts with Ph₂CN₂ to generate a metastable diazoalkane adduct, which eliminates N₂ at 60 °C to yield a paramagnetic Ni₂(μ-CPh₂) complex. The Ni₂(μ-CPh₂) complex undergoes carbene transfer to t-BuNC via an initial isonitrile adduct, which, upon heating, releases free t-BuNCCPh₂. Based on this sequence of stoichiometric reactions, a catalytic carbene transfer reaction is demonstrated.
