Eight thiacrown ethers: 1-thia-15-crown-5, 1-thia-18-crown-6, 2,3-benzo-1,4,10-trioxa-7,13-dithiacyclopentadec-2-ene, 2,3-benzo-1,4,10,13-tetraoxa-7,16-dithiacyclooctadec-2-ene, 2,5,19,22-dibenzo-1,6,12,18,23,29-hexaoxa-9,15,26,32-tetrathiacyclote tratriaconta-3,20-diene, 2,6-benzo-1,6,12,15-tetraoxa-9,18-dithiacycloeicos-3-ene, 2,3-(4'-nitrobenzo)-1,4,10-trioxa-7,13-dithiacyclopentadec-2-ene, and 2,3-(4'-nitrobenzo)-1, 4,10,13-tetraoxa-7,16-dithiacyclooctadec-2-ene have been synthesized using three methods. All of them were identified by elemental and spectral analyses (IR, 1H NMR, MS).
