ABSTRACT

Condensation of the formyl group of Cp3Fe4(CO)4(C5H4CHO) with N-methylglycine and C60 produces Cp3Fe4(CO)4(C5H4-CHNMeCH2C60) (1), where one cyclopentadienyl ring of the tetrairon cluster is linked to a fulleropyrrolidinyl moiety. A similar reaction with the bisformyl cluster Cp2Fe4(CO)4(C5H4CHO)2 affords Cp2Fe4(CO)4(C5H4-CHNMeCH2C60)2 (2). Compounds 1 and 2 have been characterized by mass, IR, UV-Vis, and NMR spectroscopy. The electrochemistry of 1 and 2 was investigated by cyclic voltammetry and differential pulse voltammetry.
