Abstract	New bisaryl corands (crown ethers) bearing 1,2-dibenzyl- and 1,2-dibenzoylbenzene subunits have been synthesized: The reaction of 1,2-bis(2-hydroxybenzyl)benzene in base with mono-tetrahydropyranyl oligoethylene glycol tosylate, deprotection of the bis-condensation product to give a corresponding diol, tosylation of the free hydroxyls of the diol, and condensation of the ditosylate in base with 1,2-bis(2-hydroxybenzyl)benzene afforded a new type of bisaryl corand(Ⅰ) of 1,2-dibenzyl-benazene system. Oxidation of the benzylic positions of the corands (Ⅰ) furnished novel aromatic corands(Ⅱ) containing partly carbonyl functions.
