hydrogen atom is eliminated and the expected η5-(C5R5) complexes are formed. Reaction of Ru3(CO)12 with 2 leads to the binuclear η6-fulvene complex 8. The octahedral molybdenum complex9 and the square planar rhodium(I) complexes 10 and 11 which were obtained from Mo(CO)6 and [Rh(CO)2Cl]2, respectively, are rare examples of η2-(C5R5H) coordination to metal atoms.

to the π-system of the Cp ring. Zinc dichloride, which binds to the N-donor, interacts slightly with the ferrocene moiety, and the triple-decker-like complex 5 is formed. The more Lewis acidic borontrichloride interacts with the functionalized Cp ring much more strongly so that the iron(II) ion cannot compete and is eliminated. Thus the organoborane 6 with intramolecular donor coordination is formed

to the intensely coloured anionic 4 which was converted into the trimethylsilyl derivative 5. This is a suitable starting compound for the trihalotitanium and -zirconium compounds 6 and 7. The two complexes were investigated by crystal structure analyses. In both cases the quinolyl nitrogen atom is coordinated to the metal.
