Organometallic species containing two carbon–metal bonds in the same molecule (dimetallic compounds) often show special reactivity patterns and offer unique synthetic applications.[1] The chemical properties of such organometallic species depend on the nature of the two metals and their topological proximity.[2] Whereas 1, n-dimetallic species (n= 1, 3–6)[3] have been prepared by several methods and efficiently employed as multi- ...
