相转移催化剂在香豆素衍生物中的应用

Application of Phase Transfer Catalyst in the Coumarin Derivatives

为加快合成香豆素衍生物,采用PEG-400为相转移催化剂进行试验,结果证明PEG-400能明显加快7-羟基-4-甲基香豆素衍生物反应速度,且能大大提高产率。

In order to increase the speed of synthesis of 7-hydroxy-4-methy-coumarin derivatives,phase transfer catalysis of PEG400 was used.It was proved the PEG400 could significantly increase the reaction speed of 7-hydroxy-4-methy-coumarin derivatives and increase the yield greatly.
