| Abstract: | A series of aryl and ferrocenyl pyrogallol4]arenes have been synthesized by the HCl-catalyzed condensation reactions of pyrogallol
with aromatic aldehydes and ferrocenecarbaldehyde. The fully acetyl and ethoxycarbonylmethoxy derivatives were also prepared
and fully characterized. The crystal structures show that acylated phenyl pyrogallol4]arene exists in rctt (cis-trans-trans) configuration, while the corresponding ferrocenyl pyrogallol4]arene in rccc (all cis) configuration. |
