[PtCl2(H2C=CH2)]2 (2.5 mol %) and PPh3 in dioxane at 120 degrees C for 16 h led to isolation of 1-benzyl-2-methyl-4,4-diphenylpyrrolidine in 75% yield. A number of gamma- and delta-amino olefins underwent intramolecular hydroamination to form the corresponding pyrrolidine derivatives in moderate to good yield. The reaction displayed excellent functional group compatibility and low moisture sensitivity.
苄基-2,2-二苯基-4-戊烯胺与 [PtCl2(H2C=CH2)]2 (2.5 mol%) 和 PPh3 在二恶烷中的 1:2 催化混合物在 120 摄氏度反应 16 小时,导致分离出1-苄基-2-甲基-4,4-二苯基吡咯烷,产率为75%。许多γ-和δ-氨基烯烃进行分子内加氢胺化,以中等至良好的产率形成相应的吡咯烷衍生物。该反应显示出优异的官能团相容性和低湿敏性。
