Microwave‐Assisted Ruthenium‐Catalysed Olefin Metathesis in Fluorinated Aromatic Hydrocarbons: A Beneficial Combination

Abstract High conversions in ruthenium‐based olefin metathesis of demanding substrates are commonly forced by using a high loading of a catalyst and conducting reactions at elevated temperature for extended times. However, in many cases this approach is not fully effective. In this article we present that fluorinated aromatic hydrocarbons (FAH) combined with microwave (MW) irradiation using a commercially available ruthenium‐based pre‐catalyst creates attractive reaction conditions for promoting challenging olefin metathesis transformations.
