摘要：

(Chemical Equation Presented) A homogeneous catalytic complex is tagged with two ferrocenyl groups to control its solubility properties by reversible switching between its neutral and dicationic states (see scheme). This approach is carried out on an olefin-metathesis catalyst and is shown to effectively switch its catalytic activity on and off; furthermore, efficient separation of the catalyst from the reaction products and subsequent recycling of the catalyst is possible. © 2005 Wiley-VCH Verlag GmbH & Co.
