Abstract
π‐Conjugated polyene complexes of the general formula (RuClCp*)~n~(polyene) [2: n = 1, polyene = 1,4‐diphenylbuta‐1,3‐diene; 3: n = 1, polyene = 1,6‐diphenylhexa‐1,3,5‐triene; 4: n = 2, polyene = 1,8‐diphenylocta‐1,3,5,7‐tetraene; 5: n = 2, polyene = 1,10‐diphenyldeca‐1,3,5,7,9‐pentaene; 6: n = 3, polyene = 1,12‐diphenyldodeca‐1,3,5,7,9,11‐hexaene], in which each ruthenium(II) atom has Cp* (Cp* = η^5^‐C~5~Me~5~) and chlorido ligands, were prepared by treating [Ru(μ~3~‐Cl)Cp*]~4~ (1) with the corresponding α,ω‐diphenylpolyenes. All diene units of the complexes were fully metalated by the coordination of “RuClCp*” fragments in an η^4^‐s‐cis conformation. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
