| 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 thi- acrovvn 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 thi- acrown ether with sticcinyl chloride in the presence of pyridine. |
