    • However, Fürstner et al. reported an increased reaction rate for the reaction in toluene compared to the reaction in DCE (see Ref. [13]. But isomerization was negligible in DCE, and as high as 10-15% in toluene. contradiction may suggest that the polarity of the solvent is also important

    • We have also shown that a fivefold increase or a decrease of the concentration is without any influence on the outcome of the reaction, when suspecting the impurity to be the dimer resulting from cross metathesis of 1a with itself
