    • 2 solution: Addition of ca. 2 equiv of ethylene to complex 5 gives after 10 min ca. 10% of free Z-2-butene from 5 and after 1 h the ratio of 5:free Z-2-butene is 1:4.5, which is close to the equilibrium. Addition of 2 equiv of ethylene to complex 6 gives after 10 min only traces of free E-2-butene and after 1 h 10% displacement, which is still very far from the equilibrium.
