Abstract

Methylene-bridged resorcin[4]arene dimers were synthesized by the Sc(OTf)₃-catalyzed hydroxymethylation of partially acetylated resorcin[4]arenes, and their preliminary complexation properties with tetraethylammonium ion were examined in CD₃OD by ¹H NMR spectroscopy. The dimers adopted a closed capsular conformation in this solvent and bound the guest molecule into their cavity.
