Hydrocarbon-Bridged Metal Complexes, XX. - Nucleophilic Addition of Carbonyl Metallates to Cationic Hexadienyl, Cyclohexadienyl, Cycloheptadienyl, and Cyclooctadienyl Complexes of Iron and Ruthium: Heterobimetallic Complexes with η1:η4, -C6, -C7, and -C8 Hydrocarbon BridgesThe addition of Re(CO)-5, Mn(CO)-5, and [(η5-C5H5)W(CO)3]- to the cationic dienyl complexes [(η5-dienyl)M(CO)3]+ (M = Fe, Ru; dienyl = hexadienyl, cyclohexadienyl, cycloheptadienyl, cyclooctadienyl, bicyclo[5.1.0]octadienyl) gives the heterobimetallic η1:η4-hydrocarbon-bridged complexes 1 - 4, 6, 7. In solution the initial nucleophilic adduct 2e of [(η5-cyclo-hexadienyl)Ru(CO)3]+ and [Re(CO)5]- rearranges to the complex 3, in which the Re(CO)5 group is bound to a sp2 carbon atom. By using Mn(CO)-5 also the products of electron transfer between cation and anion have been observed. The crystal structures of (OC)3Fe(μ-η4:η1-hexadiene)Re(CO)5 (1), (OC)3Ru(μ-η4:η1-cyclohexadiene)Re(CO)5(3), (OC)3Fe(η4:η4-C7H9 - C7H9)Fe(CO)3 (5), (OC)3Ru(μ-η4:η1-cyclooctadiene)Re-(CO)5 (6b), and of (OC)3Fe(η4:η1-bicyclo[5.1.0]octadiene)-Re(CO)5 (7) have been determined by X-ray diffraction.
