title: Evidence for an Equilibrium between an N-heterocyclic Carbene and Its Dimer in Solution.
abstract: Evidence for the Wanzlick equilibrium between carbene 1 and dibenzotetraazafulvalene (1)(2) at ambient temperature has been found (see scheme). Enetetramines of type (1)(2) can also be cleaved by coordinatively unsaturated transition metal compounds to form dicarbene complexes.
