2,2,4,4-四甲基-3-戊酮亚胺

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

实验步骤: The imine (14 g.) in dry ether (50 ml.) was added to a suspension of lithium aluminum hydride (1.7 g.) in dry ether (50 ml.). The mixture was stirred at room temperature for 24 hours, refluxed two hours and cooled. Water (1.7 ml.), 15% sodium hydroxide solution (5 ml.) and water (5 ml.) were added cautiously in succession, the mixture filtered, concentrated and the residue distilled to afford the desired amine, b.p. 79°-81° C./40 mm. refluxed two hours cooled the mixture filtered concentrated the residue distilled

实验步骤: This was prepared by the method of J. Chem. Soc., Perkin I, 2087 (1976); ibid, 1797 (1974). Pivalonitrile (33.2 g.) and t-butyl chloride (44.4 g.) were added under nitrogen to a well stirred suspension of sodium sand (18.4 g.) in a mixture of hexane (80 ml.), tetrahydrofuran (20 ml.) and methanol (1 ml.) over one hour at 15-20° C. The mixture was stirred three hours, a solution of chlorobenzene (2 g) in tetrahydrofuran (5 ml.) added dropwise over 10 minutes and stirring continued for one hour. Methanol (20 ml.) was added with caution over 0.5 hr. followed by water until phases separated. The aqueous phase was extracted with ether and the combined organic phases dried and evaporated in vacuo. The residue was distilled to afford di-t-butylketone imine, b.p. 62°-63° C./19 mm. This was prepared by the method of J The mixture was stirred three hours stirring separated The aqueous phase was extracted with ether the combined organic phases dried evaporated in vacuo The residue was distilled
