摘要： 3,19-二羟基-1-硫杂-5,8,11,14,17-五氧杂环二十烷(简称二羟基硫杂20-冠-6)在一缩二乙二醇二甲醚和氢化钠存在下可与卤代烷顺利地进行醚化反应,得到双己氧基、双十二烷氧基、双十六烷氧基、双节氧基和双烯丙氧基硫杂20-冠-6,同时也得到了单己氧基、单十二烷氧基、单十六烷氧基和单辛氧基单羟基疏杂20-冠-6副产物。二羟基硫杂冠醚可顺利地与丁二酰氯缩聚,得到主链含硫杂冠醚基团的聚酯。

Abstract: Etherification of 3,19-dihydroxy-1-thia-5,8,11,14,17-pentaoxa-cycloicosane with a series of alkyl,alkenyl,and arylalkyl halides takes place smoothly in diglyme and in the presence of NaHas a base. Dihexyloxy,didodecyloxy,dihexyldecyloxy,dibenzyloxy,and diallyloxy thia-20-crown-6 were prepared via the etherification,and four monolariat thiacrovvn ethers were also obtained as by prodticts. A polyester with thiacrown ether moieties incorporated in main chain can be obtained easily by polycondensation of dihydroxy thiacrown ether with sticcinyl chloride in the presence of pyridine.

Key words: crown ether, polymeric crown ether, lariat thiacrown ether, polyester, esterifica- tion, polycondensation, synthesis
