Versuchsvorschrift
1,1-Diphenylhydrazine hydrochloride (1.2 equiv., 0.6 mmol, 135 mg), bromobenzene (1.0 equiv., 0.5 mmol, 0.05 mL), Pd(OAc)2 (0.01 equiv, 0.005 mmol, 2 mg), BINAP (0.01 equiv., 0.005 mmol, 3 mg), and NaOtBu (2.8 equiv., 1.4 mmol, 134 mg) and toluene (3 mL) were added to an oven dried test tube which was capped with a septum and purged briefly with argon (˜1 min.) and then heated to 80° C. for 4 hours. The reaction was then cooled to room temperature, diluted with Et2O (2 mL), filtered through Celite and concentrated under vacuum. The crude mixture was purified by flash column chromatography (5% EtOAc/Hex) to give the title product as a white solid (123 mg, 0.47 mmol, 95% yield).
