“…[3] Based on these results, Herrmann stated that Wanzlick's equilibrium exists between stable carbenes and the corresponding eneteramines and that the equilibrium depends on several factors. [4] Wanzlick, again in 1970, noticed that deprotonation of an imidazolium salt by potassium tertiary butoxide yielded an imidazol-2-ylidene, which, however, was trapped but not isolated. [5] Nevertheless his contributions in the chemistry of NHCs stimulated much related research.…”
