Reaktionsschritte

Acetylacetonatobis(ethylene)rhodium(I) (0.3 mmol), (S)-(−)-2,2′-Bis(diphenyl-phosphino)-1,1′-binaphthalene (0.045 mmol), 4-(trifluoromethyl)phenylboronic acid (2 mmol), K2CO3 (0.5 mmol), and but-2-enoic acid amide (1 mmol) are added into a 25-mL round-bottomed flask containing a magnetic stirrer bar, a septum inlet, and a reflux condenser. The flask is flashed with argon and then charged with 1,4-dioxane (3 mL) and de-ionized H2O (0.5 mL). The reaction mixture is stirred for 16 hours at 100° C. The (R)-3-(4-trifluoromethylphenyl)butyramide is extracted with ethyl acetate, washed with brine, and dried over anhydrous magnesium sulfate. Chromatography over silica gel gives the desired product.
