A convenient method for the synthesis of bis-(4-alkyl-2-hydroxyphenoxy
) alkoxy ethers, precursors to highly lipophilic, alkylbenzo-substitut
ed crown ethers, is described. Thirteen isomerically-pure, bis-t-alkyl
benzo crown ethers were prepared. The solid-state structures of three
representative, bis-t-octylbenzo crown ethers are reported, representi
ng the first structures ever reported for t-octylbenzocrown ethers. Pu
