Eine Einfache Methode Zur Synthese Kationischer Metallorganischer Schwefeldioxid‐Komplexe Durch Metall‐Metall‐Bindungsspaltung

A Simple Method for the Preparation of Cationic Organometallic Sulfur Dioxide Complexes by Metal-Metal Bond Cleavage [Co(CO)4SO2]+ AsF (9) is isolated from the reaction of Co2(CO)8 (8) with AsF5 in liquid SO2. Similarly the known complexes [M(CO)5SO2]+ AsF6− [M = Mn, Re (6a, 6b)] or [η5-CpFe(CO)2-SO2]+ AsF (7) can be prepared by metal-metal bond cleavage from M2(CO)10 and [η5-CpFe-(CO)2]2, respectively.
