4’,4”(5”)-Diacrylamidodibenzo-18-crown-6 (4), 4’,4”(5”)-Diacrylamido-5’,5”(4”)-di-tertbutyldibenzo-18-crown-6 (8) and 4’,4”(5”)-diacrylamidodibenzo-21-crown-7 (12) were synthesized through amide coupling reaction. The dibenzo crown ethers were nitrated using conc.HNO3 and glacial acetic acid to give dinitro derivatives, which followed by reduction using Pd/C with hydrazine hydrate to obtain diamine derivative and finally formation diacrylamide using acrylic acid via amide coupling reaction. This method has great potential for synthesis of diacrylamide derivatives of dibenzo crown ethers. The targeted compounds were obtained in good yields.
