【摘要】 本文报导了以Pd（OH）₂/C为催化剂,将4′-酰基本并-15-冠-5催化氢化为相应的4′烷基苯并-15-冠-5的新的合成方法。此法具有反应时间短、步骤简单、后处理容易、收率高等优点,为烷基取代苯并冠醚的制备开辟了一条新的途径。更多还原

【Abstract】 4’-Alkylsubstituted benzo-15-crown-5 can be successfully prepared by catalytic hydrogenation of the corresponding 4’-acylsubstituted benzo-15-crown-5 rwith Pd （OH）₂/C. This New preparation method is characteristic of shorter reaction time, simple procedure, easier treating and purification of the products. It gives high yields and paves a new way for the preparation of stronger organophilic alkylsubstituted benzocrown ethers.更多还原
