摘要/Abstract

摘要： 本文选用我国天然生漆经催化氢化制成饱和漆酚为起始原料,或以二酚类化合物为原料,采用相转移催化方法合成了六种新的二氯化物中间体和在3′-位上含有一个正十五烷基取代的新型冠醚——不对称饱和漆酚冠醚(Ⅰ)—(Ⅳ)。并对其合成方法进行了研究,发现十六烷基三甲基硫酸氢铵、四丁基硫酸氢铵等是该反应有效的相转移催化剂。

Abstract: Anumber of new unsymmetric saturated urashiol crown ethers are synthesized by the method of phase transfer catalysis.The reaction takes place in the presence of sodium hydroxids solution containing an optimun quantity of about 0.4 molar of the a: imonium salt.The bis(chloroalkoxy)-dcrivatives, the intermediates needed in the synthesis, are prepared in good yields from catechol, resorcin, hydroquinone and saturated urachiol by the same method.The catalysts which gave good results are tetrabutylammonium hydrogen sulfate, hexadeyltrimethylammonium hydrogen sulfate etc..
