Versuchsvorschrift

Add chloro(1,5-cyclooctadiene)iridium(I) dimer (0.39 g, 0.59 mmol) to 3,3-dimethylbutan-1-ol (3.00 g, 29.35 mmol), vinyl acetate (10.11 g, 117.42 mmol) and sodium carbonate (1.87 g, 17.61 mmol) in benzene (10 mL) at room temperature. Boil under nitrogen 12 hours. Cool to room temperature and filter. Distill the filtrate and collect fraction boiling ˜125° C.-130° C. Flush through a silica gel pad with hexanes and concentrate to provide the title compound.
