 Title    Übergangsmetall-Methylen-Komplexe, X [1] Methylen-und Alkyl-Eisen-Komplexe aus Diazoalkanen. Molekülstruktur von //-Carbonyl-//-feri-butoxycarbonyl-methylen- bis [carbonyl(^ 5 -cyclopentadienyl)eisen] (Fe-Fe) Transition Metal Methylene Complexes, X [1J Methylene and Alkyl Iron Complexes from Diazoalkanes. Molecular Structure of //-Carbonyl-^-Jerf-butoxycarbonyl-methylene- bis[carbonyl(if-cyclopentadienyl)iron] (Fe-Fe)  
 Abstract    The novel doubly bridged /i-methylene iron complexes /M-[C(H)C02R]-^-C0[(??5.C5H5)Fe(C0)]2 (R = C2H5: 3a; R — ^Hg: 3b) have been syn-thesized by low-temperature photolysis of the corresponding alkyldiazoacetates 2 a and 2 b, resp., in the presence of [(r? 5 -CsH5)Fe(CO)2]2 (1) and characterized by means of their analytical data and IR, X H NMR and mass spectroscopy. The geometry of 3 b has been established by single crystal X-ray diffraction techniques. cr-Alkyl iron complexes of the type (^ 5 -C5H5)Fe(C0)2[CHRR'] are accessible from the corresponding diazoalkanes N2 = CRR'.
