For now three years, we have been developing new classes of N-Heterocyclic Carbenes (NHCs), incorporating a functionalized and modulable unit as integral part of the heterocyclic backbone. We present here a part of our results concerning the chemistry of the imidazol-2-ylidene series, which represent the most studied and used NHC family until now.[1,2]This approach allows, in particular, a post-complexation functionalization and the fine-tuning of the electronic properties of the carbene centre, as well as the access to new types of carbenes, such as the amido-aminocarbenes or the amido-amidinocarbenes.[1] (a) Benhamou, L.; Vujkovic, N.; Ce�sar, V.; Gornitzka, H.; Lugan, N. l.; Lavigne, G., Organometallics 2010,  29, 2616; (b) Benhamou, L.; C�sar, V.; Gornitzka, H.; Lugan, N.; Lavigne, G., Chem.
