Multi-component reactions involving group 6 Fischer carbene complexes: a source of inspiration for future catalytic transformations

[摘要]：The ability of heteroatom stabilized Fischer carbene complexes (FCCs) to participate in multicomponent reactions (MCRs) has become a characteristic of such organometallics, particularly of chromium carbenes. This feature article updates the main results in this field during the last lustrum, highlighting the ability of FCCs for the construction of densely functionalized frameworks, mainly through the successive incorporation of unsaturated moieties (alkynes, CO ligands, ... ) in a sequential manner. Examples where up to seven components are coupled will be presented.
