Abstract
The preferred conformations in solution for substituents onsym-dibenzo-14-crown-4 ethers are shown by NMR to depend on the atom, carbon or oxygen, linking the substituent to the crown ring.

Carbon-13 and proton NMR spectra were recorded on a Bruker MSL-400 spectrometer operating at 100.613 and 400.13 MHz, respectively. 0.1 M crown ether solutions in CDCl3 for13C and in toluene-d8 for1H were studied at 303K.
NOESY spectra were performed in the phase-sensitive mode with a mixing time of 700 ms at 303K. The spectra were recorded by using 256×1K data points with zero-filling to 1K×1K data points.
