Abstract

Three new tetraoxaparacyclophanes containing two biphenyl nuclei connected with oxypolymethyleneoxy bridges in the respective 4, 4′-positions, such as 1, 5, 18, 22- tetraoxa [5.0. 5.0] paracyclophane I 3, 1, 6, 19, 24-tetraoxa-[6.0. 6.0] paracyclophane I 4, and 1, 7, 20, 26-tetraoxa [7.0. 7.0] paracyclophane I 5, were synthesized. The UV, IR, and NMR spectra of these paracyclophanes were compared with those of the corresponding open- ...
