Multimetal Fischer carbene complexes of Group VI transition metals : synthesis, structure and substituent effect investigation

Abstract

The activation of simple organic molecules by more than one transition metal constitutes an area of research that has grown in importance. The applications of carbenes as active or auxiliary ligands in organic synthesis and catalysis, however, are mostly focused on monocarbene systems. Examples of large assemblies of carbene units (carbene supramolecular chemistry) are scarce and only a few carbene complexes are known to be part of small metal organic frameworks (MOFs). In fact very few studies on multimetal carbene complexes or multicarbene metal complexes have been recorded.
