Abstract
|
|
|
|
Two new crown ethers containing nitrogen and sulfur atoms adjacent to the crown rings were prepared. 4'-Benzothiazolylbenzo-12-crown-4 (1) or 4'-benzothiazolylbenzo-15-crown-5 (2) were synthesized by reaction of 2-aminothiophenol with 4'-formylbenzo-12-crown-4 (3) or 4'-formylbenzo-15-crown-5 (4) respectively. (3) and (4) were obtained by reaction of 3, 4-dihydroxybenzaldehyde with tri- or tetraethyleneglycol ditosylate. Triethyleneglycol ditosylate or tetraethyleneglycol ditosylate were synthesized by reaction of p-toluenesulfonylchloride with triethyleneglycol or tetraethyleneglycol in the presence of sodium hydroxide.
