摘要

摘要本文讨论了在金催化剂体系下,2 -甲基萘氧化制维生素K3的过程。该催化过程是在高交联聚苯乙烯的基础上,用前驱体- HAuCl4·2H2O和Ph3PAuCl溶液浸渍合成的。采用以Ph3PAuCl为原料合成的金催化剂体系,得到主产物- 2-甲基-1,4-萘醌-,产率为72%。

Catalytic synthesis of 2-methyl-1,4- naphthoquinone in 1%Au/HPS presence
Abstract In this paper, theoxidation process of 2 -methylnaphthalene to vitamin K3, using a gold catalyst systems will be discussed. This catalysis process is based on the hypercrosslinked polystyrene, synthesized by the impregnation with solutions of precursors − HAuCl4·2H2O and Ph3PAuCl. The use of gold catalyst system, which has been synthesized using Ph3PAuCl, allows to obtain the main product − 2-methyl-1,4-naphthoquinone − with 72% yield.
