By analysisingthe mechanism of these reactions such as the template effect,the fittable templateion,reaction conditions and the orders of adding reaction substances have been changed. All that haveimproved the yields of these crown ethers effectly. Also,the opration of separation and purifying have been simplized successfully. 冠醚 模板效应 合成 crown ether template effect synthesis O623.423 1996-02-01 2021-04-01 2
