Synthesis of Anthraqui none Derivatives Author: Ying-Mei Liu, Shuenn-Jyi Sheu(Department of Chemistry, National Taiwan Normal University)

Abstract：

Fourteen anthraquinone derivatives had been synthesized via six major routes: p-chlorophenol and phthalic anhydride via the condenstion and substitution reactions led compound 1~4 ; pyrocatechol and phthalic anhydride via the condensation and substitution reactions led compound 5~6; o-cresol and phthalic anhydride via the condensation reaction led compound 7; phenol and phthalic anhydride via the condensation and substitution reactions led compound .8~10; gallic acid and benzole acid via the condensation and substitution reactions led compound 11~12; gallic acid via the self-condensation and substitution reactions led compound 13~14.
The c=o and O-H stretching vibration of these compounds were found in the regions of 1780-1640 cm-1 and 3500-3200cm-1, and the detailed differences were discussed.
