Carbene Formation and Transfer at a Dinickel Active
Site
Posted on 2018-06-22 - 14:50
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. On the basis of this sequence of stoichiometric reactions, a catalytic
carbene transfer reaction is demonstrated.
