Iron Se-bonded mono-selenocarbonates CpFe(CO)2SeCO2R: the first selenocarbonate complexes
摘要:
The reactivity of the iron selenide complex (mu-Se)[CpFe(CO)(2)](2) toward chloroformates, ROCOCl, has been studied and the products CpFe(CO)(2)SeCO2R [R =Me (1), Et (2), iso-Bu (3), Ph (4), 2-C6H4Cl (5), 4-C6H4Cl (6), and 4-C6H4NO2 (7)] have been obtained. The novel complexes, 1-7, have been characterized by elemental analyses, IR and H-1 NMR spectroscopy. The solid state structure of CpFe(CO)(2)SeCO2Et 2, was determined by an X-ray crystal structure analysis. (C) 2004 Elsevier B.V. All rights reserved.
