Evidence for transmetalation of zirconacyclopentadiene to cobalt complex
Transmetalation reaction of zirconacyclopentadienes with cobalt(III) complex, CpCo(PPh3)I-2, proceeded to afford (cyclobutadiene)cobalt(l) complexes, CPCO(C4R4). The structure of one of the cobalt complexes was verified by X-ray structure analysis.
