摘要: 将水溶性手性二胺 (S,S)-1,2-二苯基乙二胺二磺酸钠 ((S,S)-DPENDS) 与钌膦配合物 ([RuCl2(TPPTS)2]2) 原位生成的催化剂用于催化水相中苄叉丙酮的不对称加氢反应. 在优化条件下, 羰基加氢产物 4-苯基-3-丁烯-2-醇的选择性可达 96.0%, 对映选择性可达 71.2%. 经正己烷简单萃取后即可实现催化剂与加氢产物的分离, 循环使用 5 次后, 目标产物 4-苯基-3-丁烯-2-醇选择性和对映选择性没有明显下降.

关键词: 钌膦配合物, 苄叉丙酮, 水相, 不对称加氢, 对映选择性

Abstract: The asymmetric hydrogenation of benzalacetone catalyzed by RuCl2(TPPTS)2-(S,S)-DPENDS in water medium was investigated. The selectivity of 96.0% for 4-phenyl-3-butene-2-ol and ee value of 71.2% were obtained. The catalyst could be reused five times without evident loss of catalytic activity and enantioselectivity.

Key words: ruthenium monophosphine complex, benzalacetone, water medium, asymmetric hydrogenation, enantioselectivity
