Mesoionic carbene ligand

Poly-NHC Ligands Containing Abnormal, Remote, or Mesoionic Carbenes 216... [Pg.203]

The statements abnormal and mesoionic carbenes (aNHCs and MICs) are synonyms and are referred to free carbenes for which it is not possible to draw a structure resonance formula without formal charges (Fig. 6). Differ-endy, remote carbenes (rNHCs) are carbenes without any heteroatom in the a and positions of the carbene center. These three types of ligands are characterized by a different structure with respect to the one usuaUy owned by NHCs. In the case of normal carbenes (nNHCs), the carbene donor is stabilized by the presence in the a and a positions of two heteroatoms. To emphasize this difference, aNHCs, MICs, and rNHCs are also caUed... [Pg.216]
