Versuchsvorschrift

Tetrakis(triphenylphosphine)-palladium (0) (1.48 g, 1.3 mmol) was added to a solution of (9) (13.8 g, 26 mmol) and (8) (22.6 g, 77 mmol) in a mixture of ethanol (100 mL), 2M aqueous sodium carbonate (100 mL) and toluene (300 mL) that had been deoxygenated with argon. The solution was deoxygenated and heated at reflux for 16 hours, then poured into methanol. The resulting brown precipitate was filtered, dissolved in chloroform, washed with brine, and dried over magnesium sulfate. The solution was poured into methanol, and the brown precipitate filtered to give (10) (22.4 g, 99%).
