Albrecht, Martin 2008-07-28 This feature article summarizes the progress achieved thus far in using C4-bound imidazolylidenes as a new class of ligands for transition metals. Since the discovery of this unusual carbene bonding mode in 2001, various rational routes towards complexes containing C4-bound carbenes have evolved. These advances allowed for studying the impact of this new type of ligand on the transition metal center, both from a fundamental point of view as well as from a more applied perspective, in particular for catalytic applications. The promising results accomplished in this relatively short period of time demonstrate the potential of C4-bound imidazolylidenes as unique carbene ligands for inducing catalytic activity and for mediating unprecedented transformations. application/pdf https://folia.unifr.ch/global/documents/300836 https://folia.unifr.ch/documents/300836/files/albrecht_cif.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1039/b806924g info:eu-repo/semantics/openAccess License undefined Chemical Communications. - 2008, p. 3601-3610 info:eu-repo/classification/udc/54 C4-bound imidazolylidenes: from curiosities to high-impact carbene ligands http://purl.org/coar/resource_type/c_6501
