【摘要】 探讨了中性Al2O3催化下的取代β-羟基胺Schiff碱衍生物的C—C键裂解反应,结果表明,在Al2O3存在下,由取代苯甲醛与1,2-二苯基-2-氨基乙醇形成的亚胺类化合物很容易通过逆ene反应过程发生α,β-C—C键断裂,且反应不受芳醛分子中邻位基团的影响.通过跟踪反应进程,提出了可能的反应机理.更多还原

【Abstract】 The Al₂O₃ catalyzed C—C bond cleavage of β-amino alcohol Schiff base derivatives is discussd.It is found that the α,β-C—C bond of the Schiff base formed by substituted benzaldehydes and β-amino alcohol derivatives can cleave easily via a retro-ene process in the presence of Al₂O₃ and the cleavage is not affected by the neighboring group.A proposal mechanism is therefore suggested.更多还原
