Answer
![Disodium 2,2'-[(E)-1,2-ethenediyl]bis{5-[(4-ethoxyphenyl)diazenyl]benzenesulfonate}](https://static.chemtradehub.com/structs/287/2870-32-8-0a9c.webp "Disodium 2,2'-[(E)-1,2-ethenediyl]bis{5-[(4-ethoxyphenyl)diazenyl]benzenesulfonate}")
Disodium 2,2'-[(E)-1,2-ethenediyl]bis{5-[(4-ethoxyphenyl)diazenyl]benzenesulfonate} is synthesized by diazotization and coupling reactions of aromatic compounds with ethylenediamine. The reaction typically involves sodium nitrite in an aqueous medium, followed by coupling with the appropriate aromatic diazonium salt. The process requires careful control of pH and temperature to ensure high yield and selectivity.
