Pathways for reduction of nickelocene under CO
Abstract
Cyclic voltammetry under CO has been used to show that the short-lived nickelocene anion splits into NiCp and Cp–(Cp = C5H5) fragments; trapping of the NiCp moiety with CO leads to [Ni(CO)Cp]–, which under high CO pressure loses a further Cp– to give Ni(CO)4.
