Since the discovery of ferrocene and the sandwich-type complexes, the development of organometallic chemistry took its course like an avalanche and became one of the scientific success stories of the second half of the twentieth century. Based on this development, the traditional boundaries between inorganic and organic chemistry gradually disappeared and a rebirth of the nowadays highly important field of homogeneous catalysis occurred. It is fair to say that despite the fact that the key discovery, which sparked it all off, was made more than 50 years ago, organometallic chemistry remains a young and lively discipline.The MO scheme for the bis(cyclopentadienyl) metal complexes supports this proposal since the two extra electrons of Ni(C5H5)2 ... The quest for other triple- decker sandwich complexes with a bridging cyclopentadienyl ring took over a decade. ... was mainly handicapped for kinetic reasons since the exceptionally stable ferrocene with its 18-electron configuration ... Me), affording the homo- and hetero-metallic triple- decker complexes 7a12 in good to excellent yield (Scheme 6.5) .
