Abstract

Among the macrocyclic compounds reported to date, little attention has been paid to the phosphorus-containing macrocycles including cyclic phosphonates, hydrogen phosphonates, and alkyl or aryl phosphonates. These compounds are used as flame proofing agents [1, 2] and for the recognition and separation of alkali and lanthanide metals [3, 4]. Macrocycles containing phosphorus–oxygen bonds may also have special ...
