    摘要:

    具有复杂取代基团苯基衍生物的苯环选择加氢属于原子经济反应,不仅可以消除苯环对人体健康的潜在危害,而且能够赋予所合成材料以特殊功能。本文综述了保留取代基团苯环选择加氢反应的催化剂、操作条件及反应性能的研究进展,主要包括芳香二胺、芳香酯类、芳香族氨基甲酸甲酯、聚苯乙烯、联苯及双酚A等的苯环催化加氢反应。为了使苯环上取代基团不发生反应,多采用Rh、Ru、Pd和Pt等贵金属催化剂。Ni等非贵金属催化剂的活性和选择性有待进一步提高。因此,今后研究重点应是开发减量或替代贵金属的高性能催化剂。

    Abstract:

    The selective hydrogenation of the benzene ring of phenyl derivatives with complex substituent groups is an atom-economic reaction. It can not only eliminate the potential harm of benzene ring to human health, but also endow the synthesized materials with special functions. In this paper, the research progress of catalysts, operating conditions and reaction properties for selective hydrogenation of benzene rings with retained substituent groups was reviewed, mainly including the catalytic hydrogenation of benzene rings of aromatic diamines, aromatic esters, aromatic methyl carbamate, polystyrene, biphenyls and bisphenol A. In order to retain the substituent group on the reactant, the catalyst used in the above reaction was noble metals such as ruthenium, rhodium, palladium, and platinum. The activity and selectivity of non-precious metal catalysts such as Ni need to be further improved. Therefore, the future research should focus on the development of high performance catalysts with reduced or alternative noble metals.
