Synthesis and Supramolecularity of C-Phenylcalix[4] Pyrogallolarenes: Temperature Effect on the Formation of Different Isomers

Abstract

A family of C-(4-substituted phenyl)calix[ 4 Nicod , L. , Chitry , F. , Gaubert , E. , & Lemaire , M. ( 1999 ). Application of water soluble resorcinarenes in nanofiltration–complexation with caesium and strontium as targets . J. Incl. Phenom. Macro. Chem. , 34 , 143 – 151 . [Google Scholar] ]pyrogallolarene hosts was synthesized through the acid-catalyzed condensation of pyrogallol with a series of para-substituted benzaldehydes at different reaction temperatures. The effect of reaction temperature and substitution pattern on the benzaldehyde was investigated. Different isomers of C-(4-substituted phenyl)calix[ 4 Nicod , L. , Chitry , F. , Gaubert , E. , & Lemaire , M. ( 1999 ).

[Google Scholar] ]pyrogallolarene were observed at room temperature or under reflux conditions as indicated in the solid-state structures of compounds 1 and 2. The conformational rigidity of the resulting C-(4-substituted phenyl)calix[ 4 Nicod , L. , Chitry , F. , Gaubert , E. , & Lemaire , M. ( 1999 ).
