Reaktionsschritte

palladium(II) acetate (21.45 mg, 0.10 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (111 mg, 0.19 mmol) were placed in a round-bottomed vessel that was filled with nitrogen. Toluene (0.8 mL) was added and the mixture was heated to 50°C for 30 min. sodium tert-butoxide (138 mg, 1.43 mmol) was added to a second vessel and inerted with nitrogen. tert-butyl 2-(piperidin-4-yl)ethylcarbamate (342 mg, 1.5 mmol) and bromobenzene (150mg, 0.96 mmol) and toluene (1.4 mL) were added. 14/04 2009 13:57:24 +0200 The catalyst solution was added to the reagent mixture and the combined mixture was heated to reflux for several hours. The reaction did not work.
