12. 2 (5 ml) and the disubstituted olefin (1.0 mmol, 2 equiv) are added in succession. The terminal olefin (0.5 mmol, 1 equiv) is added and the septum is quickly replaced with a condenser which is connected to a nitrogen bubbler. The flask is immersed in an oil bath and refluxed (bath temperature: 45 °C) for a period of 12 hr or until the reaction is judged complete by TLC.

15. 15. In contrast, the use of neat allyl acetate provided only marginal amounts of the desired cross-product, presumably due to the statistically favored solvent dimerization which dominates the catalytic cycle.
