非均相催化剂(钯碳催化剂)一般会将芳香酮彻底还原至亚甲基产物,而不易得到苄醇类的中间还原产物。本文报道一系列氨基酮用钯碳催化剂催化氢化的结果,随酮底物含有不同种类的氨基而得到不同的氢化产物(亚甲基产物或二级醇产物),部分则不发生还原反应;分析讨论了底物所含氨基对产物的影响及其机理。结果表明,这是一个制备胺基芳香仲醇的有效方法。 Heterogeneous catalysts (palladium on carbon) generally reduce aromatic ketones to methylene products without the intermediate reduction products of benzyl alcohols. In this paper, we report the results of catalytic hydrogenation of a series of aminoketones with palladium on carbon catalyst. Different hydrogenation products (methylene products or secondary alcohol products) were obtained with different kinds of amino groups on the ketone substrate. Some of them did not undergo reduction reaction. The effects of amino groups on the products and their mechanism were discussed. The results show that this is an effective method for preparing amino aromatic secondary alcohols.
