Investigation of organolanthanide-based carbon-carbon bond formation: Synthesis, structure, and coupling reactivity of organolanthanide alkynide complexes, including the unusual structures of the trienediyl complex [(C{sub 5}Me{sub 5}){sub 2}Sm]{sub 2}[{mu}-{eta}{sup 2}:{eta}{sup 2}-Ph(CH{sub 2}){sub 2}C=C=C=C-(CH{sub 2}){sub 2}Ph] and the unsolvated alkynide [(CH{sub 2}){sub 2}Ph] and the unsolvated alkynide [(C{sub 5}Me{sub 5}){sub 2}Sm(C{triple_bond}CCMe{sub 3})]{sub 2}

Aryl alkynide ligands in organometallic samarium complexes can couple to form the [PhC=C=C=CPh]{sup 2-} trienediyl ligand in [Cp*{sub 2-} Sm]{sub 2}({mu}-{eta}{sup 2}:{eta}{sup 2}-PhC=C=C=CPh). The authors studied the generality of this set of reactions with other lanthanide centers, namely, cerium, and neodymium as well as with varied charge states of the lanthanide. Not all of the reactions occur, but for those that do, the products were characterized by NMR and X-ray crystallography.
