N,N-二甲基-3-苯基丙酰胺

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A 20-mL eggplant flask equipped with a three-way cock and a magnetic stirrer was heat dried while pumping to a vacuum of 5 Pa before its interior was purged with argon atmosphere. Into the flask, iron complex A (1.0 mg, 0.002 mmol) was admitted as catalyst and dissolved in toluene (0.5 mL). To the solution, 1,2-bis(dimethylsilyl)benzene (475 μL) was added through a syringe, and N,N-dimethyl-3-phenylpropanamide (177 mg, 1.0 mmol) was added. The solution was stirred at 100° C. for 30 minutes. Toluene was distilled off in vacuum. The crude product was purified by silica gel-packed column chromatography using hexane/ethyl acetate (10/1) as developing solvent, obtaining N,N-dimethyl-3-phenylpropylamine (159 mg, 0.83 mmol, 83%). The results are shown as Entry 4 in Table 5. The resulting amine was identified for geometry by 1H and 13C-NMR spectroscopy and IR spectroscopy.
