手性Binap-Ru(II)催化剂用于不对称加氢反应的研究进展

doi:10.6023/cjoc201606024

摘要/Abstract

手性联二萘基双膦配体Binap由一对2-二苯基膦萘基连接1和1'位组成，具C₂-对称框架轴向手性，比旋光度达到±234°.Binap配体可以和许多过渡金属形成稳定的螯合状配合物，在催化过程中通过金属中心“传递”立体空间效应，诱导不对称催化反应.针对Binap-Ru（Ⅱ）催化体系，以体系中形成的稳定配合物为主线，详细介绍反应过程中涉及到的底物分子种类、反应条件、产物的对映选择性等以及可能的反应机理，以期对该体系有深入的理解.特别关注该体系的不对称催化应用合成.

关键词: Binap配体, 手性钌配合物, 不对称催化, 反应机理, 应用

Chiral 2,2'-bis(diphenylphosphino)-1,1'-binapthyl(Binap) ligand consists of a pair of 2-diphenylphosphinonaphthyl groups connected at the 1 and 1'positions,being of the nature of the C₂-axial chirality with optical activity of ±234°.The Binap can coordinate with many transitional metals to form stable chelation complexes,effecting the chirality transfer to the metal center for function in asymmetrically catalytic reactions.This contribution is focused on the Binap-Ru(Ⅱ) catalytic system that covers the various substrates,reaction conditions,enantioselectivity of the products,reaction mechanism,and others on the basis of the prepared stable Binap-Ru(Ⅱ) complexes as the clue in the text.This study will give a deep understanding of this system especially concerning the applied catalytic synthesis of the useful organic molecules.

Key words: Binap ligand, chiral ruthenium complexes, asymmetric catalysis, reaction mechanism, application
