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.
