The right mix does the trick: Elusive {Ni(0)(eta(6)-arene)} moieties can be dramatically stabilized by the N-heterocyclic silylene ligand 1, which has a zwitterionic mesomeric structure. The sigma, pi-acid-base synergism between nickel and 1 explains the unexpectedly high stability of the new silylene complexes 2, which enables arene exchange studies at a Ni(0) center. Addition of B(C(6)F(5))(3) to 2 affords the zwitterionic silylene complex 3 (see scheme, R=2,6-iPr(2)C(6)H(3)).
