Abstract
The novel doubly bridged μ-methylene iron complexes μ-[C(H)CO2R]-μ-CO[(η5-C5H5)Fe(CO)]2 (R = C2H5: 3a; R = tC4H9: 3b) have been synthesized by low-temperature photolysis of the corresponding alkyldiazoacetates 2a and 2b, resp., in the presence of [(η5-C5H5)Fe(CO)2]2 (1) and characterized by means of their analytical data and IR, 1H NMR and mass spectroscopy. The geometry of 3b has been established by single crystal X-ray diffraction techniques. δ-Alkyl iron complexes of the type (η5-C5H5)Fe(CO)2[CHRRʹ] are accessible from the corresponding diazoalkanes N2 = CRRʹ.
