Recent advances in the field of multicarbene and multimetal carbene complexes of the Fischer-type

This review article covers the development of Fischer carbene complexes since the year 2000, with specific focus on carbene complexes bearing metal-containing fragments as substituents, as well as multicarbene systems. The role of the metal-containing substituents on the character and reactivity of such complexes are discussed. In addition, larger systems containing more than one carbene ligand are also covered (rod-like biscarbenes, chelates, macrosystems, etc.) in terms of the synthesis, reactivity and structural aspects.

► Recent advances of multicarbene and multimetal systems.
► Focus on structural aspects of Fischer carbene complexes.
► Applications of multimetal–multicarbene complexes.
