    • Without the addition of the ethylene gas, the substrates reported in Table 9 may have been difficult to turn over in the catalytic cycle, and the Grubbs II catalyst may be trapped as the vinylcarbene ruthenium complex shown below. This intermediate could consume the Grubbs II catalyst and decompose after extended exposure to elevated temperatures. For a DFT study of the mechanism of enyne metathesis and the effect of ethylene gas, see
