Notes:
H,H and P,H coupling constants and variable-temperature 1H and 13C NMR spectra and 13C T1 values for some macrocyclic dithiophosphonic esters are presented to show that these compounds possess reduced flexibility in comparison with crown ethers. The NMR spectroscopic results are supported by an x-ray structure which shows a highly strained ring system.
