This microreview summarizes our work on new reactions to obtain ruthenium(II) binuclear species with seven conjugated carbon atoms between the remote metals in very mild conditions via CC bond formation. (i) The treatment of trans-[Cl(dppe) 2RuCCCCSiMe 3] with [Fe(C 5H 5) 2]PF 6 leads to an unprecedented metal-assisted [2+2] coupling reaction between C γC δ bonds to produce trans-[Cl(dppe) 2RuCC CCHC(C H 2)CCRu(dppe) 2Cl]PF 6 including a cyclobutenyl bridge. (ii) Addition of a cationic allenylidene trans-[ClRu(dppe) 2(CCC(CH 2R 1)R 2)]BF 4 (R 1=H, CH 3; R 2=CH 3, Ph) on the C γC δ bond of the diyne trans-[Cl(dppe) 2RuCCCCH] leads to ruthenium bimetallic complexes trans-[Cl(dppe) 2RuCCC(CH 3)C(R 1)C(R 2)CCRu(dppe) 2Cl]BF 4 containing a planar delocalized “W”-shaped C 7 bridge with tunable pendant groups. These complexes display attractive redox and optical properties with a highly delocalized charge over the conjugated carbon atoms. The crystal structures of trans-[Cl(dppe) 2RuCCC(CH 3)C(H)C(CH 3)CCRu(dppe) 2Cl]BF 4 and of the annealated complex were solved.
