Abstract
Synthesis, characterization, and reactivity studies of oligocyclopentadienyl transition
metal complexes, namely those of fulvalene, tercyclopentadienyl, quatercyclopentadienyl,
and pentacyclopentadienyl(cyclopentadienyl) are the subject of this account. Thermal-,
photo-, and redox chemistries of homo- and heteropolynuclear complexes are described.
