Anion is superior: NHC-based triorganozincates, from mononuclear to trinuclear, have been synthesized. The NHC-based triorganozincate chain (see scheme; left) was transformed into an abnormal carbene (aNHC)-complexed zinc ring (right) by reaction with MeOTf, closing the aNHC-Group 12 complexes gap.
