1. Predict the structures of the products (if any would be expected) from the following: (a) CpRu(CO)2Me + PPh3, (b) Cp2ZrHCl + butadiene, (c) CpFe(CO)2Me + SO2, (d) Mn(CO)5CF3 + CO.
2. In the pyrolysis of TiMe4, both ethylene and methane are observed; explain.
3. An oxidative addition to a metal complex A is found to take place with MeOSO2Me but not with i-PrI. A second complex, B, reacts with i-PrI but not with MeOSO2Me. What mechanism(s) do you think is (are) operating in the two cases? Which of the two complexes, A or B, would be more likely to react with MeI? What further tests could you apply to confirm the mechanism(s)?
